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.

Input: Consider Input: 5, 20, ['5377', 'j', 'j', '1767', '2103', '9547', 'I', 'M', '4067', '2571', 'V', 'Z', 'O', '3421', 'V', 'v', '4919', 'X', '307', 'M', '1603']

Output: M307X4919vV3421OZV25714067MI95472103
