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: 10, 12, ['9333', '4709', 'w', '4565', 'r', '8133', 'd', 'f', 'e', '787', '5633', 'P', 'j']
Example Output: P5633787
