text: Minimum number of Appends of X or Y characters from the end to the front required to obtain given string | C # program for the above approach ; Function to find the minimum operations required to get the given string after appending m or n characters from the end to the front of the string in each operation ; Store the original string ; Stores the count of operations ; Traverse the string ; Cut m letters from end ; Add cut m letters to beginning ; Update j ; Check if strings are the same ; Cut n letters from end ; Add cut n letters to beginning ; Update j ; Check if strings are the same ; Update the turn ; Driver Code ; Given string S ; Function Call
