Maximize palindromic strings of length 3 possible from given count of alphabets | Function to count maximum number of palindromic string of length 3.
Stores the final count of palindromic strings.
Traverse the array.
Increment res by arr [ i ] / 3 , i . e forming string of only i + ' a ' character.
Store remainder.
Increment c1 by one , if current frequency is 1.
Increment c2 by one , if current frequency is 2.
Count palindromic strings of length 3 having the character at the ends different from that present in the middle.
Update c1 and c2.
Increment res by 2 * c2 / 3.
Finally print the result.
Driver Code.
Given array.
Function Call"
How can the above be solved in Python?
