Given a non-negative integernum, repeatedly add all its digits until the result has only one digit. For example: Givennum = 38, the process is like:3 + 8 = 11,1 + 1 = 2. Since2has only one digit, return it. 思路:取各位数字相加,直至相加结果为一位数(<9),考虑边界情况 思路:规律...

We used the str() class to convert the number to a string. This is necessary because adding leading zeros to a number causes a SyntaxError. The str.zfill() method takes the width of the string and left-fills the string with 0 digits to make it of the specified width. main.py Copied...
