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:
2, 5, ['B', 'I', 'X', '2953', 'J', '303', '6521', 'l', 'o', '5279', 'd', 'l', '9565']

Ex Output:
J2953XI
