Palindromic strings of length 3 possible by using characters of a given string | Function to print all palindromic strings of length 3 that can be formed using characters of string S.
Stores the count of character.
Traverse the string S.
Stores all palindromic strings.
Iterate over the charchaters over the range [ ' a ' , ' z ' ].
If Hash [ ch ] is equal to 2.
Iterate over the characters over the range [ ' a ' , ' z ' ].
Stores all the palindromic string.
Push the s into the set st.
If Hash [ i ] is greater than or equal to 3.
Iterate over charchaters over the range [ ' a ' , ' z ' ].
Stores all the palindromic string.
If Hash [ j ] is positive.
Push s into the set st.
Iterate over the set.
