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: 3, 11, ['k', '3147', '895', '3989', '2311', '2865', '6011', '365', '6165', 'T', 'W', '1471', 'n', '6321', 'N', 'F', '4729', 'n', 'P']
Example Output: WT61653656011286523113989895
