Given an array of integers A of length N. For each index i, find number of indices j(j!=i) such that gcd(A[i],A[j])>1.
Constraints:
N<=1e5
1<=A[i]<=N
Example:
A = [4,3,2,4] output = [2,0,2,2]
A = [2,3,6,4,6,5] output = [3,2,4,3,4,0]

Hello Codeforces!
I have a doubt in today contest problem A :(https://mirror.codeforces.com/contest/1557/problem/A)
I submitted solution in which I have used accumulate function to get sum of all elements of vector but it gave me WA.
And finally I got AC in which I find sum by traversing all elements.
Is there any difference in both methods to get sum of all elements of vector?
Here are the links of my both submissions :
125393659 — WA
125396830 — AC
Please help me to find out the error in code(using accumulate function).
Thanks in advance:)
UPD : Resolved
