akhauriyash/Code-Regression huggingface dataset:
Chef has a binary array in an unsorted manner. Cheffina challenges chef to find the transition point in the sorted (ascending) binary array. Here indexing is starting from 0.
Note: Transition point always exists.

-----Input:-----
- First-line will contain $T$, the number of test cases. Then the test cases follow. 
- Each test case contains two lines of input, $N$.
- N space-separated binary numbers. 

-----Output:-----
For each test case, output in a single line answer.

-----Constraints-----
- $1 \leq T \leq 10$
- $1 \leq N \leq 10^5$

-----Sample Input:-----
1
5
0 1 0 0 1

-----Sample Output:-----
3

-----EXPLANATION:-----
binary array in sorted form will look like = [0, 0, 0, 1, 1]

You have been recently hired as a developer in CodeChef. Your first mission is to implement a feature that will determine the number of submissions that were judged late in a contest.
There are $N$ submissions, numbered $1$ through $N$. For each valid $i$, the $i$-th submission was submitted at time $S_i$ and judged at time $J_i$ (in minutes). Submitting and judging both take zero time. Please determine how many submissions received their verdicts after a delay of more than $5$ minutes.

-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first line of the input contains a single integer $N$.
- $N$ lines follow. For each valid $i$, the $i$-th of these lines contains two space-separated integers $S_i$ and $J_i$.

-----Output-----
For each test case, print a single line containing one integer — the number of submissions for which the judging was delayed by more than 5 minutes.

-----Constraints-----
- $1 \le T \le 100$
- $1 \le N \le 100$
- $1 \le S_i \le J_i \le 300$ for each valid $i$

-----Subtasks-----
Subtask #1 (100 points): original constraints

-----Example Input-----
1
5
1 3
4 4
4 10
1 11
2 7

-----Example Output-----
2

-----Explanation-----
Example case 1: The delays of the respective submissions are $2$ minutes, $0$ minutes, $6$ minutes, $10$ minutes and $5$ minutes. Only submissions $3$ and $4$ are delayed by more than $5$ minutes, hence the answer is $2$.

You are playing a game where you have been sent in a town to collect 10 types of coin and their symbol are defined with $A, B, C, D, E, F, G, H , I, J$. In that town every enemy have a coin. By killing one you will get a coin from that enemy. Each enemy have only a unique coin.
The challange of the game is You have to collect all the coin and only then you will get the victory. You are a brave gamer so you took this hard challange and successfully finished it. After finishing, you are thinking of the game. You know the order off collecting coin. Now you are thinking how many enemy did you have killed?
Can you solve that out?

-----Input:-----
First line of the input is an integer $T$.Next T line consists of a string which denotes the order of your collecting coins. The string consists of Uppercase latin latter only and from A to J.

-----Output:-----
Print T line, in each line an integer with the number of enemy you have killed in the operation.

-----Constraints-----
- $1 \leq T \leq 5000$

-----Sample Input:-----
1

This is probably the simplest problem ever. You just need to count the number of ordered triples of different numbers (X1, X2, X3), where Xi could be any positive integer from 1 to Ni, inclusive (i = 1, 2, 3).
No, wait. I forgot to mention that numbers N1, N2, N3 could be up to 1018. Well, in any case it is still quite simple :)
By the way, because of this the answer could be quite large. Hence you should output it modulo 109 + 7. That is you need to find the remainder of the division of the number of required triples by 109 + 7.

-----Input-----
The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows. The only line of each test case contains three space-separated integers N1, N2, N3.

-----Output-----
For each test case, output a single line containing the number of required triples modulo 109 + 7.

-----Constraints-----
- 1 ≤ T ≤ 1000
- 1 ≤ Ni ≤ 1018

-----Example-----
Input:
5
3 3 3
2 4 2
1 2 3
25 12 2012
1 1 2013

Output:
6
4
1
578880
0

-----Explanation-----
Example case 1. We have the following triples composed of different numbers up to 3:
(1, 2, 3)
(1, 3, 2)
(2, 1, 3)
(2, 3, 1)
(3, 1, 2)
(3, 2, 1)
Example case 2. Here the triples are:
(1, 3, 2)
(1, 4, 2)
(2, 3, 1)
(2, 4, 1)
Example case 3. Here the only triple is (1, 2, 3).
Example case 4. Merry Christmas! 
Example case 5. ... and Happy New Year! By the way here the answer is zero since the only choice for X1 and for is X2 is 1, so any such triple will have equal numbers.

-----Input-----
The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows. The only line of each test case contains three space-separated integers N1, N2, N3.

-----Output-----
For each test case, output a single line containing the number of required triples modulo 109 + 7.

-----Constraints-----
- 1 ≤ T ≤ 1000
- 1 ≤ Ni ≤ 1018

-----Example-----
Input:
5
3 3 3
2 4 2
1 2 3
25 12 2012
1 1 2013

Output:
6
4
1
578880
0

-----Explanation-----
Example case 1. We have the following triples composed of different numbers up to 3:
(1, 2, 3)
(1, 3, 2)
(2, 1, 3)
(2, 3, 1)
(3, 1, 2)
(3, 2, 1)
Example case 2. Here the triples are:
(1, 3, 2)
(1, 4, 2)
(2, 3, 1)
(2, 4, 1)
Example case 3. Here the only triple is (1, 2, 3).
Example case 4. Merry Christmas! 
Example case 5. ... and Happy New Year! By the way here the answer is zero since the only choice for X1 and for is X2 is 1, so any such triple will have equal numbers.

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 is very fond of horses. He enjoys watching them race. As expected, he has a stable full of horses. He, along with his friends, goes to his stable during the weekends to watch a few of these horses race. Chef wants his friends to enjoy the race and so he wants the race to be close. This can happen only if the horses are comparable on their skill i.e. the difference in their skills is less.
There are N horses in the stable. The skill of the horse i is represented by an integer S[i]. The Chef needs to pick 2 horses for the race such that the difference in their skills is minimum. This way, he would be able to host a very interesting race. Your task is to help him do this and report the minimum difference that is possible between 2 horses in the race.

-----Input:-----
First line of the input file contains a single integer T, the number of test cases.

Every test case starts with a line containing the integer N.

The next line contains N space separated integers where the i-th integer is S[i].

-----Output:-----
For each test case, output a single line containing the minimum difference that is possible.

-----Constraints:-----
1 ≤ T ≤ 10
2 ≤ N ≤ 5000
1 ≤ S[i] ≤ 1000000000

-----Example:-----Input:
1
5
4 9 1 32 13

Output:
3

Explanation: The minimum difference can be achieved if we pick horses with skills 1 and 4 for the race.

Chef belongs to a very rich family which owns many gold mines. Today, he brought N gold coins and decided to form a triangle using these coins. Isn't it strange?
Chef has a unusual way of forming a triangle using gold coins, which is described as follows:
- He puts 1 coin in the 1st row.
- then puts 2 coins in the 2nd row.
- then puts 3 coins in the 3rd row.
-  and so on as shown in the given figure.
Chef is interested in forming a triangle with maximum possible height using at most N coins. Can you tell him the maximum possible height of the triangle?

-----Input-----
The first line of input contains a single integer T denoting the number of test cases. 
The first and the only line of each test case contains an integer N denoting the number of gold coins Chef has.

-----Output-----
For each test case, output a single line containing an integer corresponding to the maximum possible height of the triangle that Chef can get.

-----Constraints-----
- 1 ≤ T ≤ 100
- 1 ≤ N ≤ 109

-----Subtasks-----
- Subtask 1 (48 points) : 1 ≤ N ≤ 105
- Subtask 2 (52 points) : 1 ≤ N ≤ 109

-----Example-----
Input3
3
5
7

Output2
2
3

-----Explanation-----
- Test 1: Chef can't form a triangle with height > 2 as it requires atleast 6 gold coins.
- Test 2: Chef can't form a triangle with height > 2 as it requires atleast 6 gold coins.
- Test 3: Chef can't form a triangle with height > 3 as it requires atleast 10 gold coins.
