Algorithm: Max Counters

Question

I have the following problem:

You are given N counters, initially set to 0, and you have two possible operations on them:

• increase(X) − counter X is increa

Answer 1

def solution(N, A):
    # write your code in Python 2.6
    res = [0] * N
    m = 0
    minValue = 0
    for x in A:
        if 1 <= x <= N:
            res[x - 1] = max(res[x - 1], minValue) + 1
            if res[x - 1] > m:
                m = res[x - 1]
        else:
            minValue = m
    for i in xrange(N):
        res[i] = max(res[i], minValue)
    return res
