akhauriyash/Code-Regression huggingface dataset:
There are N towns on a line running east-west.
The towns are numbered 1 through N, in order from west to east.
Each point on the line has a one-dimensional coordinate, and a point that is farther east has a greater coordinate value.
The coordinate of town i is X_i.
You are now at town 1, and you want to visit all the other towns.
You have two ways to travel:
 - Walk on the line.
Your fatigue level increases by A each time you travel a distance of 1, regardless of direction.
 - Teleport to any location of your choice.
Your fatigue level increases by B, regardless of the distance covered.
Find the minimum possible total increase of your fatigue level when you visit all the towns in these two ways.

-----Constraints-----
 - All input values are integers.
 - 2≤N≤10^5
 - 1≤X_i≤10^9
 - For all i(1≤i≤N-1), X_i<X_{i+1}.
 - 1≤A≤10^9
 - 1≤B≤10^9

-----Input-----
The input is given from Standard Input in the following format:
N A B
X_1 X_2 ... X_N

-----Output-----
Print the minimum possible total increase of your fatigue level when you visit all the towns.

-----Sample Input-----
4 2 5
1 2 5 7

-----Sample Output-----
11

From town 1, walk a distance of 1 to town 2, then teleport to town 3, then walk a distance of 2 to town 4.
The total increase of your fatigue level in this case is 2×1+5+2×2=11, which is the minimum possible value.

Almir had a small sequence $A_1, A_2, \ldots, A_N$. He decided to make $K$ copies of this sequence and concatenate them, forming a sequence $X_1, X_2, \ldots, X_{NK}$; for each valid $i$ and $j$ ($0 \le j < K$), $X_{j \cdot N + i} = A_i$.
For example, if $A = (1, 2, 3)$ and $K = 4$, the final sequence is $X = (1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3)$.
A pair $(i, j)$, where $1 \le i < j \le N$, is an inversion if $X_i > X_j$. Find the number of inversions in the final sequence $X$.

-----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 each test case contains two space-separated integers $N$ and $K$.
- The second line contains $N$ space-separated integers $A_1, A_2, \ldots, A_N$.

-----Output-----
For each test case, print a single line containing one integer ― the number of inversions in the sequence $X$.

-----Constraints-----
- $1 \le T \le 1,000$
- $1 \le N \le 100$
- $1 \le K \le 10^6$
- $1 \le A_i \le 10^9$ for each valid $i$

In order to celebrate Twice's 5th anniversary, Tzuyu and Sana decided to play a game.

Tzuyu gave Sana two integers $a$ and $b$ and a really important quest.

In order to complete the quest, Sana has to output the smallest possible value of ($a \oplus x$) + ($b \oplus x$) for any given $x$, where $\oplus$ denotes the bitwise XOR operation. 


-----Input-----

Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 10^{4}$). Description of the test cases follows.

The only line of each test case contains two integers $a$ and $b$ ($1 \le a, b \le 10^{9}$).


-----Output-----

For each testcase, output the smallest possible value of the given expression.


-----Example-----
Input
6
6 12
4 9
59 832
28 14
4925 2912
1 1

Output
10
13
891
18
6237
0



-----Note-----

For the first test case Sana can choose $x=4$ and the value will be ($6 \oplus 4$) + ($12 \oplus 4$) = $2 + 8$ = $10$. It can be shown that this is the smallest possible value.

Chef was bored staying at home in the lockdown. He wanted to go out for a change. Chef and Chefu are fond of eating Cakes,so they decided to go the Cake shop where cakes of all possible price are available .
They decided to purchase cakes of equal price and each of them will pay for their cakes. Chef only has coins of denomination $N$ whereas Chefu has that of denomination $M$.
So they want your help to find out the minimum amount to be spent in order to purchase the cakes.

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input, two integers $N, M$. 

-----Output:-----
For each testcase, output in a single line answer the minimum amount to be spent in order to purchase the cake.

-----Constraints-----
- $1 \leq T \leq 1000$
- $2 \leq N,M \leq 10^7$

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

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.

Given a string consisting of only lowercase English alphabets, your task is to find the smallest palindromic substring.
In case there are multiple palindromic substrings of the same length present, print the lexicographically smallest substring. 
Formally, a substring is a contiguous sequence of characters within a string. So in a string "abcdef", "abc" is a substring whereas "adf" is not a substring.
A palindrome is a word, phrase, or sequence that reads the same backwards as forwards, e.g. madam or mom.

-----Input:-----
- First-line will contain $T$, the number of test cases. Then the test cases follow. 
- Each test case contains of two lines of input, two integers.
- First, we have a single integer $N$ which signifies the length of the substring.
- Next, we have a string of length $N$ that only has lowercase English alphabets.

-----Output:-----
For each testcase, output in a single line the shortest palindromic substring.

-----Constraints-----
- $1 \leq T \leq 100$
- $2 \leq N \leq 10^5$

-----Sample Input:-----
2
2
zy
1
cd

-----Sample Output:-----
y
c

-----EXPLANATION:-----
There are only two possibilities. "z" and "y". Since both of them have the same length. We print the lexicographically smaller substring which is y.

There are N towns on a line running east-west.
The towns are numbered 1 through N, in order from west to east.
Each point on the line has a one-dimensional coordinate, and a point that is farther east has a greater coordinate value.
The coordinate of town i is X_i.
You are now at town 1, and you want to visit all the other towns.
You have two ways to travel:
 - Walk on the line.
Your fatigue level increases by A each time you travel a distance of 1, regardless of direction.
 - Teleport to any location of your choice.
Your fatigue level increases by B, regardless of the distance covered.
Find the minimum possible total increase of your fatigue level when you visit all the towns in these two ways.

-----Constraints-----
 - All input values are integers.
 - 2≤N≤10^5
 - 1≤X_i≤10^9
 - For all i(1≤i≤N-1), X_i<X_{i+1}.
 - 1≤A≤10^9
 - 1≤B≤10^9

-----Input-----
The input is given from Standard Input in the following format:
N A B
X_1 X_2 ... X_N

-----Output-----
Print the minimum possible total increase of your fatigue level when you visit all the towns.

-----Sample Input-----
4 2 5
1 2 5 7

-----Sample Output-----
11

From town 1, walk a distance of 1 to town 2, then teleport to town 3, then walk a distance of 2 to town 4.
The total increase of your fatigue level in this case is 2×1+5+2×2=11, which is the minimum possible value.

Chef Two and Chef Ten are playing a game with a number $X$. In one turn, they can multiply $X$ by $2$. The goal of the game is to make $X$ divisible by $10$.
Help the Chefs find the smallest number of turns necessary to win the game (it may be possible to win in zero turns) or determine that it is impossible.

-----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 and only line of each test case contains a single integer denoting the initial value of $X$. 

-----Output-----
For each test case, print a single line containing one integer — the minimum required number of turns or $-1$ if there is no way to win the game.

-----Constraints-----
- $1 \le T \le 1000$
- $0 \le X \le 10^9$

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

$Gogi$, $Tapu$ and $Sonu$ are the elite members of $Tapu$ $Sena$. $Gogi$ is always stoned and asks absurd questions, But this time he asked a question which seems to be very serious and interesting. $Tapu$ wants to solve this question to impress $Sonu$. He  gave an array of length N to $Tapu$, $Tapu$ can perform the following operations exactly once:
- Remove any subarray from the given array given the resulting array formed after the removal is non-empty.    
- Reverse the whole array.
Remember you can’t shuffle the elements of the array.
Tapu needs to find out the maximum possible GCD of all the numbers in the array after applying the given operations exactly once. Tapu is very weak at programming, he wants you to solve this problem so that he can impress $Sonu$.

-----Input:-----
- The first line contains $T$, the number of test cases.
- For each test case
-FIrst line contains $N$.
- Last line contains $N$ numbers of the array. 

-----Output:-----
A single integer in a new line, maximum possible GCD. 

-----Constraints-----
- $1 \leq T \leq 10^2$
- $1 \leq N \leq 10^4$
- $1 \leq a[i] \leq 10^9$

Summation of N for all testcases is less than $10^6$
