C - 100 to 105/三井住友信託銀行プログラミングコンテスト2019

Problem

100, 101, 102, 103, 104, 105を組み合わせてXが作れるか否か判定する。

1 <= X <= 100,000

Submission

def solve():
    X = int(input())
    quotient = X // 100
    remainder = X % 100
    if 0 <= remainder and remainder <= 5 * quotient:
        print(1)
        exit()
    print(0)
solve()

0 <= (Xを100で割った余り) <= 5× (Xを100で割って切り捨てた値)
が成立するかどうか調べる。
