HDU 1020 - Encoding

Easy Problems -_-||

Input:

AABBBCDDDD

Output:

To practice more and simple example of input and output, not exactly algorithm, just practice. ..



*. -> Using string (char array) may be better.

#include<iostream>
#include<cstdio>

using namespace std;

void fRead(char cPrevious) {
char a;
int t = 1;
while(true) {
scanf("%c", &a);
if(cPrevious == a)
t++;
else
break;
}
if(t == 1)
cout  << cPrevious;
else
cout << t << cPrevious;

if(a == '\n')
cout << endl;
else
fRead(a);
}
int main() {
int n;
char a;
scanf("%d", &n);
while(n--) {
scanf("%c", &a);
scanf("%c", &a);
fRead(a);
}
}
