we define function f(i,j) on array A as below:
f(i,j) = (i-j)^2 + (A[i+1] + A[i+2] + A[i+3] + ... + A[j])^2
find the minimum value of function f.
2 <= A.size <= 10^5
-10^4 <= A[i] <= 10^4

We've got n nonnegative numbers (a[i]) . We want to find the pair with maximum gcd. For example if we have:
2 4 5 15
gcd(2,4)=2
gcd(2,5)=1
gcd(2,15)=1
gcd(4,5)=1
gcd(4,15)=1
gcd(5,15)=5
The answer is 5.
n<100,000 and a[i]<100,000
I have an O(n*sqrt(n)) algorithm is there more efficient algorithm like O(n*logn) or O(n)?

Hi. I need an Implementation of Fenwick tree in C++ that can support lazy propagation. Can you help me?
