Definition: 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.
Input: 5, 14, ['Q', 'J', '9253', '4175', '7793', 'Q', 'J', 'h', '9947', '7779', '5005', 'n', 'w', 'K', '2775', '9301', '6247']
