#### Answer:
Expert Solution

Setup
Let any string be represented by an array of characters.
For example, the given string CABAAXBYA can be respresented by an array S[] such that
S[1] = C
S[2] = A
S[3] = B
S[4] = A
S[5] = A
S[6] = X
S[7] = B
S[8] = Y
S[9] = A
The below algorithm will accept such array as input. Note, index starts from 1, not zero
