akhauriyash/Code-Regression huggingface dataset:
You are given a sequence $A_1, A_2, \ldots, A_N$. For each valid $i$, the star value of the element $A_i$ is the number of valid indices $j < i$ such that $A_j$ is divisible by $A_i$.
Chef is a curious person, so he wants to know the maximum star value in the given sequence. Help him find it.

-----Input-----
- The first line of the input contains a single integer $T$ which denotes the number of test cases.
- The first line of each test case contains a single integer $N$ .
- The second line of each test case 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 maximum star value.

-----Constraints-----
- $1 \le T \le 10$
- $1 \le N \le 10^5$
- $1 \le A_i \le 10^6$ for each valid $i$ 
- Sum of $N$ over all test cases does not exceed $100,000$.

-----Subtasks-----
Subtask #1 (20 points): sum  of $N$ over all test cases does not exceed $5,000$
Subtask #2 (80 points): original constraints

-----Example Input-----
1
7
8 1 28 4 2 6 7

-----Example Output-----
3

-----Explanation-----
$A_5 = 2$ divides $4$, $28$ and $8$, so its star value is $3$. There is no element with a higher star value.

Amit is going on a date and he wants to gift his date an array of positive numbers. But he is running short on money. He already has an array of numbers in design. Cost of an array of numbers is the sum of elements in it. But he wants to minimize the cost of making it. 
So he does the following number of operations one by one for any number of times:
He chooses two adjacent elements ,replace them by one element with value = XOR of the two numbers. This operation reduces length of array (and elements are re-numerated accordingly)
Find the minimum amount of money that Amit needs to spend to gift his date.

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains of $2$ lines of input, first line contains a single integer $N$ and the second line contains $N$ elements - $A1,A2,A3,.....,AN$ 

-----Output:-----
For each testcase, output in a single line answer denoting the minimum cost

-----Constraints-----
- $1 \leq T \leq 10$
- $1 \leq N \leq 10^5$
- $0 \leq Ai \leq 10^9$ for $1\leq i \leq N$

-----Sample Input:-----
3
5
8 4 1 5 0
5
1 2 4 0 8
2
10 10

-----Sample Output:-----
8
15
0

-----EXPLANATION:-----
For first case,
This array is :
$[8,4,1,5,0] -> [8,4,4,0] -> [8,0,0]$. Sum=$8$ So the answer is 8.

Chef played an interesting game yesterday. This game is played with two variables $X$ and $Y$; initially, $X = Y = 0$. Chef may make an arbitrary number of moves (including zero). In each move, he must perform the following process:
- Choose any positive integer $P$ such that $P \cdot P > Y$.
- Change $X$ to $P$.
- Add $P \cdot P$ to $Y$.
Unfortunately, Chef has a bad memory and he has forgotten the moves he made. He only remembers the value of $X$ after the game finished; let's denote it by $X_f$. Can you tell him the maximum possible number of moves he could have made in the game?

-----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 $X_f$.

-----Output-----
For each test case, print a single line containing one integer — the maximum number of moves Chef could have made.

-----Constraints-----
- $1 \le T \le 10^5$
- $1 \le X_f \le 10^9$

-----Example Input-----
3
3
8
9

-----Example Output-----
3
5
6

-----Explanation-----
Example case 2: One possible sequence of values of $X$ is $0 \rightarrow 1 \rightarrow 2 \rightarrow 3 \rightarrow 5 \rightarrow 8$.

The chef is having one array of N natural numbers(numbers may be repeated). i.e. All natural numbers must be less than N. Chef wants to rearrange the array and try to place a natural number on its index of the array, i.e array[i]=i. If multiple natural numbers are found for given index place one natural number to its index and ignore others.i.e. arr[i]=i and multiple i found in array ignore all remaining i's If any index in the array is empty place 0 at that place. i.e. if for arr[i], i is not present do arr[i]=0.

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains two lines of input.
- First-line has $N$ denoting the size of an array.
- Second-line has $N$ space-separated natural numbers.

-----Output:-----
For each test case, output in a single line with the new rearranged array.

-----Constraints-----
- $1 \leq T \leq 10^3$
- $2 \leq N \leq 10^3$
- $arr[i] \leq N-1$

-----Sample Input:-----
2
2
1 1
4
1 1 2 1

-----Sample Output:-----
0 1
0 1 2 0

-----EXPLANATION:-----
For 1) $1$ occurs twice in the array hence print 0 at 0th index and 1 at 1st index
For 2) $1$ occurs thrice and 2 once in the array hence print 0 at 0th index and 1 at 1st index, 2 at 2nd index and 0 at 3rd index.

There are $5$ cities in the country.
The map of the country is given below.
The tour starts from the red city.

Each road is associated with a character.
Initially, there is an empty string.
Every time a road has been travelled the character associated gets appended to the string.
At the green city either the string can be printed or the tour can be continued.
In the problem, you are given a string tell whether it is possible to print the string while following the rules of the country?

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains a single line of input, a string $ s  $. The string consists only of $0's$ and $1's$.

-----Output:-----
For each testcase, output "YES" or "NO" depending on the input.

-----Constraints-----
- 
$1 \leq T \leq 10000$
- 
$1 \leq length of each string \leq 10000$
- 
$ 1 \leq Summation length \leq 10^5$

Chef had a sequence of positive integers with length $N + K$. He managed to calculate the arithmetic average of all elements of this sequence (let's denote it by $V$), but then, his little brother deleted $K$ elements from it. All deleted elements had the same value.
Chef still knows the remaining $N$ elements — a sequence $A_1, A_2, \ldots, A_N$. Help him with restoring the original sequence by finding the value of the deleted elements or deciding that there is some mistake and the described scenario is impossible.
Note that the if it is possible for the deleted elements to have the same value, then it can be proven that it is unique. Also note that this value must be a positive integer.

-----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 three space-separated integers $N$, $K$ and $V$.
- 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 value of the deleted elements, or $-1$ if there is a mistake.

-----Constraints-----
- $1 \le T \le 100$
- $1 \le N, K \le 100$
- $1 \le V \le 10^5$
- $1 \le A_i \le 10^5$ for each valid $i$

You are given a string s of length n.
Does a tree with n vertices that satisfies the following conditions exist?
 - The vertices are numbered 1,2,..., n.
 - The edges are numbered 1,2,..., n-1, and Edge i connects Vertex u_i and v_i.
 - If the i-th character in s is 1, we can have a connected component of size i by removing one edge from the tree.
 - If the i-th character in s is 0, we cannot have a connected component of size i by removing any one edge from the tree.
If such a tree exists, construct one such tree.

-----Constraints-----
 - 2 \leq n \leq 10^5
 - s is a string of length n consisting of 0 and 1.

-----Input-----
Input is given from Standard Input in the following format:
s

-----Output-----
If a tree with n vertices that satisfies the conditions does not exist, print -1.
If a tree with n vertices that satisfies the conditions exist, print n-1 lines.
The i-th line should contain u_i and v_i with a space in between.
If there are multiple trees that satisfy the conditions, any such tree will be accepted.

-----Sample Input-----
1111

-----Sample Output-----
-1

It is impossible to have a connected component of size n after removing one edge from a tree with n vertices.

Simple, remove the spaces from the string, then return the resultant string.

~~~if:c
For C, you must return a new dynamically allocated string.

We have a sequence A of N non-negative integers.
Compute the sum of \prod _{i = 1} ^N \dbinom{B_i}{A_i} over all sequences B of N non-negative integers whose sum is at most M, and print it modulo (10^9 + 7).
Here, \dbinom{B_i}{A_i}, the binomial coefficient, denotes the number of ways to choose A_i objects from B_i objects, and is 0 when B_i < A_i.

-----Constraints-----
 - All values in input are integers.
 - 1 \leq N \leq 2000
 - 1 \leq M \leq 10^9
 - 0 \leq A_i \leq 2000

-----Input-----
Input is given from Standard Input in the following format:
N M
A_1 A_2 \ldots A_N

-----Output-----
Print the sum of \prod _{i = 1} ^N \dbinom{B_i}{A_i}, modulo (10^9 + 7).

-----Sample Input-----
3 5
1 2 1

-----Sample Output-----
8

There are four sequences B such that \prod _{i = 1} ^N \dbinom{B_i}{A_i} is at least 1:
 - B = \{1, 2, 1\}, where \prod _{i = 1} ^N \dbinom{B_i}{A_i} = \dbinom{1}{1} \times \dbinom{2}{2} \times \dbinom{1}{1} = 1;
 - B = \{2, 2, 1\}, where \prod _{i = 1} ^N \dbinom{B_i}{A_i} = \dbinom{2}{1} \times \dbinom{2}{2} \times \dbinom{1}{1} = 2;
 - B = \{1, 3, 1\}, where \prod _{i = 1} ^N \dbinom{B_i}{A_i} = \dbinom{1}{1} \times \dbinom{3}{2} \times \dbinom{1}{1} = 3;
 - B = \{1, 2, 2\}, where \prod _{i = 1} ^N \dbinom{B_i}{A_i} = \dbinom{1}{1} \times \dbinom{2}{2} \times \dbinom{2}{1} = 2.
The sum of these is 1 + 2 + 3 + 2 = 8.
