String compression

#1

why this code is not passing 2nd and 3rd test case
#include
#include
using namespace std;
int main() {
string s;
int freq[256]={0};
cin>>s;
for(int i=0;i<s.length();i++)
{
freq[s[i]]++;
}
char ch;
for(int i=0;i<256;i++)
{
if(freq[i]>0)
{
cout<<char(i)<<freq[i];
}
}
return 0;
}

@dreamerekta please save your code on ide.codingblocks.com and share the link here

#3

@dreamerekta your logic is flawed because
for inputs like
aabbaa
the answer should be a2b2a2 but your program will not give an output like this.

#4

now i have sort the string …and it is giving correct output for inputs like you told me…but yet not passing the test cases 2nd and 3rd
#include
#include
#include
using namespace std;
int main() {
string s;
int freq[256]={0};
cin>>s;
sort(s.begin(),s.end());
for(int i=0;i<s.length();i++)
{
freq[s[i]]++;
}
char ch;
for(int i=0;i<256;i++)
{
if(freq[i]>0)
{
cout<<char(i)<<freq[i];
}
}
return 0;
}

#5

@dreamerekta please save your code on ide.codingblocks.com and share the link, I have asked you before as well. Sharing code like this changes the formatting and the indentation is gone and a lot of keywords also go missing.
