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: 4, 6, ['7933', '4733', 'l', 'h', '3833', 'm', '4937', 'l', 'x', '381', 'j']
Example Output: m3833h

Example Input: 1, 2, ['z', '1877']
