In this task, you are given inputs i,j, and A, where i and j are integers and A is a list. You need to concatenate all elements of A from the ith element to the jth element, and print the resultant string. i and j will be non-negative, and will always have a value less than the length of A. i will always be less than j.

1, 3, ['K', 'T', 'K']
KTK
Given the list ['K', 'T', 'K'], we need to concatenate the elements from 1st to 3rd element. The final result is "KTK"..
