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.

Example Input: 3, 16, ['z', '2195', 'S', '1703', '3137', 'Q', 'D', 'C', 'u', 'F', 'q', 'x', 'B', 'T', 'b', 't', 'l', '3965', '5177', '7607', 't']
