Question: A string s is a circular shift of a string t if it matches when the characters of one string are circularly shifted by some

A string s is a circular shift of a string t if it matches when the characters of one string are circularly shifted by some number of positions. For example, ACTGACG is a circular shift of TGACGAC, and vice versa. Detecting this condition is important in the study of genomic sequences. Write a function isCircularShift() that checks whether two given strings s and t are circular shifts of one another.
