正常情况:此解法是利用迭代,使用两层循环,外层判断大小,内层进行数据计算,先对10取余,再除以10,进入下一位接着计算,如果算到最后一位,跳出内层循环,此时还要加上对10取余的余数,因为内层循环只是做判断,然后将算出的和赋值给num,sum归为0,再开始下一次的循环。 publicintaddDigits2(intnum) {if(num<10) {...
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. 解题思路: 假设输入的数字是一个5位数字num,则num的各位分别为a、b、c...

I don't think we can use any constants in the calculation. The s parameter in round could be not a constant although I suspect some backends only will allow constants here. If it is not a constant then we don't know a lot. If the number turns out to be negative the scale could ev...
