Find the string present at the middle of a lexicographically increasing sequence of strings from S to T | Function to print the string at the middle of lexicographically increasing sequence of strings from S to T.
Stores the base 26 digits after addition.
Iterete from right to left and add carry to next position.
Reduce the number to find the middle string by dividing each position by 2.
If current value is odd , carry 26 to the next index value.
