A program to determine the sum of digits of a given non-negative integer number using a while loop is presented in Program. The program segment given below does the same thing using a do...while loop.
sum = 0; while (num > 0) digit = num % 10; sum += digit; num /= 10; Note that this program works correctly even if the given number is zero. The complete program given below accepts a number from the keyboard, determines the sum of its digits and prints the sum. #include <std...

C. Vlad and a Sum of Sum of Digits 分析 在给定的数据规模下,可以直接暴力计算出每个数的数位之和,求出前缀和后就可以在O(1)的时间复杂度下返回答案,因为数位拆分的时间复杂度为O(nlogn),所以总的时间复杂度为O(nlogn+t),其中t为查询次数。
