Set .discard(), .remove() & .pop()

    Why this works? .pop() removes an element randomly. But hackrrank assumes always min element is removed.

    n = int(input())
s = set(map(int, input().split()))
N = int(input())

for _ in range(N):
    cmd = input().split()
    if cmd[0] == 'pop':
        # remove the smallest item to match HackerRank's pop behavior
        s.remove(min(s))
    elif cmd[0] == 'remove':
        s.remove(int(cmd[1]))
    elif cmd[0] == 'discard':
        s.discard(int(cmd[1]))

print(sum(s))
