Make the string in AP by changing a character | Function to modify the given string and find the index where modification is needed.
Array to store the ASCII values of alphabets.
Loop to compute the ASCII values of characters a - z.
Set to store all the possible differences between consecutive elements.
Loop to find out the differences between consecutive elements and storing them in the set.
Checks if any character of the string disobeys the pattern.
Constructing the strings with all possible values of consecutive difference and comparing them with staring string S ..
