#1

question says whose frequency is once should not print .
Why my code not work fully?

#2

Please do code (or make changes ) using char array not with string

this is because you approach is will not work in all cases

here you have to compression the string

For INPUT
aabbaacc
Your output
a4b2c2
but correct output is
a2b2a2c2

correct approach
