Write a program in C to find the sum of digits of a number using recursion. Pictorial Presentation:Sample Solution:C Code:#include <stdio.h> int DigitSum(int num); int main() { int n1, sum; printf("\n\n Recursion : Find the sum of digits of a number :\n"); printf("---\n"...
we determined the sum of digits of a non-negative integer number by determining the least significant digit and then removing it from given number. In this example, we generalize this technique to determine the sum of digits of any non-negative integer number. To separate the digits of given ...

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 of the digits of 336 is 12 Pictorial Presentation: Sample Solution: C Code: #include <stdio.h>intmain(){inta,x=0,y;// Prompt user for inputprintf("Input a positive number less than 500: \n");// Read the input valuescanf("%d",&a);y=a;if(y<1||y>999){//...

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。
CodeForces 489C (贪心) Given Length and Sum of Digits...,题意:找出m位且各个数位数字之和为s的最大和最小整数,不包括前导0(比如说003是非法的),但0是可以的。分析:这题是用贪心来做的,同样是m位数,前面的数字越大这个数就越大。所以写一个can(intm,ints)函数,来
