    The shortest method for the above python code

    return sum(1 for x in range(len(s)) if sum(s[x:x+m]) == d)

      Well done!

      Im not sure of this solution. This will not be working with this input:

      5
1 2 1 3 3
3 2

      The output should be 2 but will be 3 because it will count last digit of the series 3. This solution does not consider what if solution will be shorter than a month digit.

      Sure, this will pass all validators but still... :).

        return sum(1 for x in range(len(s)) if sum(s[x:x+m]) == d and len(s[x:x+m]) == m )

      That't beutiful thank you for sharing : i did this way but we can make way shorter by yours..

      1. num=0
      2. for i in range(len(s)):
      3. if sum(s[i:i+m])==d:
      4. num+=1
      5. return(num)

        List comprehension is amazing

          I agree but also his method is n * m time complexity sadly.
