I don't know how to solve it using Inclusion-Exclusion. I have DP solution.
To compute cnt value in O(1) split dp array into c[i] arrays.
Array number x has elements with numbers { x, x + c[i], x + c[i] * 2... }.
cnt value is equal to sum of integers on some subarray of array number j % c[i].
You have to construct prefix-sum array for each array to cumpute it.
