6976번: Divisibility by 11

구현 문제였습니다.

📕 풀이방법

📔 입력 및 초기화

 1. test case t를 선언 후 입력해줍니다. 2. t만큼 for loop를 수행하며 num을 선언해 입력받습니다. 3. 정답을 출력하기 위해 변수ori를 선언해 num값을 저장합니다.

📔 풀이과정

 num이 100이상인 동안 while loop를 수행합니다.

 1. 뺄 변수 sub를 선언하고 10으로 나눈 나머지 값을 int형으로 저장합니다.

 2. num을 10으로 나눠줍니다. //는 결과를 자동으로 int형으로 casting해줍니다.

📔 정답출력

조건에 따라 출력해줍니다.

📕 Code

t = int(input())

for i in range(t):
    num = int(input())
    ori = num
    print(num)
    while(num >= 100):
        sub = int(num % 10)
        num //= 10
        num -= sub
        print(num)
    if(ori % 11 == 0):
        print(f"The number {ori} is divisible by 11.")
    else:
        print(f"The number {ori} is not divisible by 11.")
    print()
