    I have the same idea as you, but why are most of my test cases failing ?

    static int solve(int n, int[] s, int d, int m)
    {
        int start=0,end=m-1;
        int sum=0,num=0;
        for(int i=start ; i<=end && end<s.length ; i++)
        {
            sum+=s[i];
            if(i==end)
            {
                if(sum == d)
                {
                    num++;
                    sum=0;
                    i=start+1;
                    start++;
                    end++;
                }
                else
                {
                    sum=0;
                    i=start+1;
                    start++;
                    end++;
                }
            }
        }
        return num;
    }

      Hey, it's probably not working because in this code i is getting changed to start + 1 and then getting incremented again as part of the for loop. 

      if(sum == d)
                {
                    num++;
                    sum=0;
                    i=start+1;
                    start++;
                    end++;
                }
                else
                {
                    sum=0;
                    i=start+1;
                    start++;
                    end++;
                }

      Hope this helps.

        include

        using namespace std;

        int main() { int i,n,sum=0,date,month,num[1000],count=0,j; cin>>n; for(i=0;i>num[i]; } cin>>date>>month; for(i=0;i

      A good constructive tip: extract common code like:

      if(sum == d) {
    num++;
} else {
    start++;
}

i=start+1;
sum=0;
start++;
end++;

      It's More readable
