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: 1, 7, ['3145', '4447', 'h', '1723', '2791', '8085', 'H', 'R', '5457', 'F', 'P', 'N', 'u', 's']
Example Output: H808527911723h44473145

Example Input: 5, 6, ['9707', '3873', '6063', '8877', 'l', '9711', 's', 'M']
Example Output: 9711l

Example Input: 2, 9, ['W', '7003', 'X', '8725', 'P', '911', 't', 'd', 'm', 'o']
