Codeforces Problem 102B Solution in (C++)

Welcome:

The question to the problem can be found here:

Explanation:

1.Enter the integer as an character.

2.This will separate the biggest integer into smaller pieces.

3.Convert the pieces into integer and then add using a variable and store in the array s.

4.Convert the piece into character array

5.Continue until only 1 character is present.

6.Happy Coding.

Code:

#include<bits/stdc++.h>

using namespace std;

char s[100000];

int main(){

int cnt=0;

cin>>s;

while(s[1]){

cnt++;

int res =0;

for(int i=0;s[i];i++)

    res+= s[i] - '0';

    sprintf(s,"%d",res);

}

cout<<cnt;

return 0;}
