Array Manipulation

  • gg_germain + 0 comments

    Just improved your code a bit. - split() is slightly faster than split("") - an if was not needed as always true - variables names fit those used in the exercise

    if __name__ == "__main__":
    n, m = [int(n) for n in input().split()]
    l = [0]*(n+1)
    for _ in range(m):
        a, b, k = [int(n) for n in input().split()]
        l[a-1] += k
        l[b] -= k;
    max = a = 0
    for i in l:
       a+=i;
       if max<a:
            max=a;
    print(max)
