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, 4, ['1751', '8755', 'p', 'k', '8177', '3087', 'T', '8495', 'G', '2089', '8811', '3295', '3157', 'o', 'F', 'w', '6933', '5097']

Ex Output:
