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.

Ex Input:
8, 11, ['3075', 'B', '4901', '6425', '7345', 'm', 'c', 'x', '7607', '2945', 'F', '5025', '3131', 'N', '6337', 'n', 'l', 'i', '3281', 'J', '5825', '9765', '8305', 'B', 'O', '1927', '6017', 'F', 'B', 'D']

Ex Output:
F29457607x
