String compression

#1

test case 3 is not passing

#include
using namespace std;
#include
int main() {
string s1;
getline(cin,s1);
string ans="";
int i=0;
int j=0;

while(i<s1.length()){
	while(j<s1.length() && s1[i]==s1[j]){
		j++;
	}
    int count=j-i;
	ans=ans+s1[i]+char(count+'0');
	i=j;
}
s1=ans;
cout<<s1<<endl;
return 0;

}

Hello @rabimajumder08,

ans=ans+s1[i]+char(count+‘0’);

This line is wrong if the count is more than 9 let’s say 12 then it will show the wrong output.

Correct way,

ans=ans+s1[i]+to_string(count);

to_string converts numbers into string.
