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 find all elements of A from the ith element to the jth element, reverse the order in which they occur, and then concatenate them to output 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. Perform the operations in order, i.e., do not concatenate the elements and then reverse the string.

Ex Input:
13, 16, ['w', '1993', 'O', '7475', 'Q', '1431', 'X', '5305', '8051', 'p', 'P', 'Z', 'S', '4277', 'G', 's', 'n', '4837', 'l', '5727', '3519']

Ex Output:
sG4277S
