akhauriyash/Code-Regression huggingface dataset:
You are playing a very popular game called Cubecraft. Initially, you have one stick and want to craft $k$ torches. One torch can be crafted using one stick and one coal.

Hopefully, you've met a very handsome wandering trader who has two trade offers:  exchange $1$ stick for $x$ sticks (you lose $1$ stick and gain $x$ sticks).  exchange $y$ sticks for $1$ coal (you lose $y$ sticks and gain $1$ coal). 

During one trade, you can use only one of these two trade offers. You can use each trade offer any number of times you want to, in any order.

Your task is to find the minimum number of trades you need to craft at least $k$ torches. The answer always exists under the given constraints.

You have to answer $t$ independent test cases.


-----Input-----

The first line of the input contains one integer $t$ ($1 \le t \le 2 \cdot 10^4$) — the number of test cases. Then $t$ test cases follow.

The only line of the test case contains three integers $x$, $y$ and $k$ ($2 \le x \le 10^9$; $1 \le y, k \le 10^9$) — the number of sticks you can buy with one stick, the number of sticks required to buy one coal and the number of torches you need, respectively.


-----Output-----

For each test case, print the answer: the minimum number of trades you need to craft at least $k$ torches. The answer always exists under the given constraints.

Chef loves to play with arrays by himself. Today, he has an array A consisting of N distinct integers. He wants to perform the following operation on his array A.

- Select a pair of adjacent integers and remove the larger one of these two. This decreases the array size by 1. Cost of this operation will be equal to the smaller of them.

Find out minimum sum of costs of operations needed to convert the array into a single element.

-----Input-----
First line of input contains a single integer T denoting the number of test cases. First line of each test case starts with an integer N denoting the size of the array A. Next line of input contains N space separated integers, where the ith integer denotes the value Ai.

-----Output-----
For each test case, print the minimum cost required for the transformation.

-----Constraints-----
- 1 ≤ T ≤ 10 
- 2 ≤ N ≤ 50000 
- 1 ≤ Ai ≤ 105 

-----Subtasks-----
- Subtask 1 : 2 ≤ N ≤ 15 : 35 pts 
- Subtask 2 : 2 ≤ N ≤ 100 : 25 pts 
- Subtask 3 : 2 ≤ N ≤ 50000 : 40 pts 

-----Example-----
Input
2
2
3 4
3
4 2 5

Output
3
4

-----Explanation-----Test 1 :  Chef will make only 1 move: pick up both the elements (that is, 3 and 4), remove the larger one (4), incurring a cost equal to the smaller one (3).

Chef is planning a huge party for all of you and has ordered M pizzas. He wants to invite as many people to the party. However, he knows that everyone will have exactly one slice of a pizza (regardless of the size) and he wants to make sure that he has enough pizza slices. 
Chef is very lazy and will only make a total of N straight cuts among all the pizzas. Each pizza is also of different size and to avoid the slices getting too small the chef can only make a max of Ai cuts to the ith pizza. He wants to maximize the number of slices of pizza. Since chef is busy with preparing other aspects of the party he wants you to find out the maximum number of slices he can get following the constraints. 
If a pizza is not cut at all then it is considered as 1 slice.  

-----Input-----
First line contains two integers M and N.
The second line of input contains the array A.

-----Output-----
Output a single integer - the maximum number of slices chef can get.

-----Constraints-----
- 1 ≤ M ≤ 2*105
- 1 ≤ N,Ai ≤ 2*105

-----Subtasks-----
- Subtask 1: 1 ≤ M,N ≤ 100 - 10 points 
- Subtask 2: 1 ≤ N ≤ 100, 
1 ≤ M ≤ 105 - 20 points
- Subtask 3: Original Constraints - 70 points

-----Example-----
Input:
5 10
1 2 3 4 5
Output:
31

-----Explanation-----
Example case 1. One of the optimal way to cut would be to do {0, 1,  0, 4, 5} cuts.

Zaikia has $N$ sticks of distinct positive lengths $A_1,A_2,\dots,A_N$. For no good reason at all, he wants to know if there is a triplet of sticks which when connected end-to-end will form a non-trivial triangle. Here non-trivial refers to a triangle with positive area.
Help Zaikia know if such a triplet exists or not. If such a triplet exists, help him find the lexicographically largest applicable triplet.Input
- The first line contains an integer $N$.
- The second line contains $N$ space-seperated integers $A_1,A_2,\dots,A_N$. Output
- In the first line print YES if a triplet exists or NO if it doesn't.
- If such a triplet exists, then in the second line print the lexicographically largest applicable triplet.Constraints
- $3 \leq N \leq {2}\times{10}^{5}$
- $1 \leq A_i \leq {10}^{9}$ for each valid $i$Sample Input 1

Explanation 1
There are three unordered triplets of sticks which can be used to create a triangle:
- $4,2,3$
- $4,2,5$
- $4,3,5$
Arranging them in lexicographically largest fashion
- $4,3,2$
- $5,4,2$
- $5,4,3$
Here $5,4,3$ is the lexicographically largest so it is the triplet which dristiron wantsSample Input 2

Hooray! Polycarp turned $n$ years old! The Technocup Team sincerely congratulates Polycarp!

Polycarp celebrated all of his $n$ birthdays: from the $1$-th to the $n$-th. At the moment, he is wondering: how many times he turned beautiful number of years?

According to Polycarp, a positive integer is beautiful if it consists of only one digit repeated one or more times. For example, the following numbers are beautiful: $1$, $77$, $777$, $44$ and $999999$. The following numbers are not beautiful: $12$, $11110$, $6969$ and $987654321$.

Of course, Polycarpus uses the decimal numeral system (i.e. radix is 10).

Help Polycarpus to find the number of numbers from $1$ to $n$ (inclusive) that are beautiful.


-----Input-----

The first line contains an integer $t$ ($1 \le t \le 10^4$) — the number of test cases in the input. Then $t$ test cases follow.

Each test case consists of one line, which contains a positive integer $n$ ($1 \le n \le 10^9$) — how many years Polycarp has turned.


-----Output-----

Print $t$ integers — the answers to the given test cases in the order they are written in the test. Each answer is an integer: the number of beautiful years between $1$ and $n$, inclusive.


-----Example-----
Input
6
18
1
9
100500
33
1000000000

Output
10
1
9
45
12
81



-----Note-----

In the first test case of the example beautiful years are $1$, $2$, $3$, $4$, $5$, $6$, $7$, $8$, $9$ and $11$.

Consider an infinite full binary tree (each node has two children except the leaf nodes) defined as follows. For a node labelled v its left child will be labelled 2*v and its right child will be labelled 2*v+1. The root is labelled as 1.
You are given N queries of the form i j. For each query, you have to print the length of the shortest path between node labelled i and  node labelled j.

-----Input-----
First line contains N, the number of queries. Each query consists of two space separated integers i and j in one line.

-----Output-----
For each query, print the required answer in one line.

-----Constraints-----
- 1 ≤ N ≤ 105
- 1 ≤ i,j ≤ 109

-----Example-----
Input:
3
1 2
2 3
4 3

Output:
1
2
3

-----Explanation-----
For first query, 1 is directly connected to 2 by an edge. Hence distance 1.

You have initially a string of N characters, denoted by A1,A2...AN. You have to print the size of the largest subsequence of string A such that all the characters in that subsequence are distinct ie. no two characters in that subsequence should be same.

A subsequence of string A is a sequence that can be derived from A by deleting some elements  and without changing the order of the remaining elements.

-----Input-----
First line contains T, number of testcases. Each testcase consists of a single string in one line. Each character of the string will be a small alphabet(ie. 'a' to 'z').

-----Output-----
For each testcase, print the required answer in one line.

-----Constraints-----
- 1 ≤ T ≤ 10
- Subtask 1 (20 points):1 ≤ N ≤ 10
- Subtask 2 (80 points):1 ≤ N ≤ 105

-----Example-----
Input:
2
abc
aba

Output:
3
2

-----Explanation-----
For first testcase, the whole string is a subsequence which has all distinct characters.

In second testcase, the we can delete last or first 'a' to get the required subsequence.

Chef is now a corporate person. He has to attend office regularly. But chef does not want to go to office, rather he wants to stay home and discover different recipes and cook them. 
In the office where chef works, has two guards who count how many times a person enters into the office building. Though the duty of a guard is 24 hour in a day, but sometimes they fall asleep during their duty and could not track the entry of a person in the office building. But one better thing is that they never fall asleep at the same time. At least one of them remains awake and counts who enters into the office.
Now boss of Chef wants to calculate how many times Chef has entered into the building. He asked to the guard and they give him two integers A and B, count of first guard and second guard respectively.
Help the boss to count the minimum and maximum number of times Chef could have entered into the office building.

-----Input-----
The first line of the input contains an integer T denoting the number of test cases. The description of the T test cases follows. 
Each test case consists of a line containing two space separated integers A and B.

-----Output-----
For each test case, output a single line containing two space separated integers, the minimum and maximum number of times Chef could have entered into the office building.

-----Constraints-----
- 1 ≤ T ≤ 100
- 0 ≤ A, B ≤ 1000000

We say that two integers x and y have a variation of at least K, if |x − y| ≥ K (the absolute value of their difference is at least K). Given a sequence of N integers a1,a2,...,aN and K, the total variation count is the number of pairs of elements in the sequence with variation at least K, i.e. it is the size of the set of pairs

{(i,j)|1≤i<j≤N and|ai−aj|≥K} 

For example if K = 1 and the sequence is 3,2,4 the answer is 3. If K = 1 and the sequence is 3, 1, 3 then the answer is 2.

Your task is to write a program that takes a sequence and the value K as input and computes the total variation count.

-----Input format-----
The first line contains two positive integers N and K, separated by a space.

This is followed by a line containing N integers separated by space giving the values
of the sequence.

-----Output format-----
A single integer in a single line giving the total variation count.

-----Test data-----
You may assume that all integers in the input are in the range 0 to 10^8 inclusive.

Subtask 1 (40 marks) : 1 ≤ N ≤ 4000, 1 ≤ K ≤ 10^8 
Subtask 2 (60 marks) : 1 ≤ N ≤ 65000, 1 ≤ K ≤ 10^8 

-----Sample Input-----
3 1 
3 1 3

-----Sample Output-----
2

## Task

Given a positive integer `n`, calculate the following sum: 

```
n + n/2 + n/4 + n/8 + ...
``` 

All elements of the sum are the results of integer division.

## Example

```
25  =>  25 + 12 + 6 + 3 + 1 = 47
```
