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.

14, 16, ['1911', 'u', '1355', 'M', 'K', '1179', 'd', 'k', '5233', 'j', 'c', 'G', 'C', '4147', '6939', 'X', 'y', '4461']
X69394147
Given the list ['1911', 'u', '1355', 'M', 'K', '1179', 'd', 'k', '5233','j','c','G','C','4147','6939','X','y'], we need to find the elements within the range 14 ~ 16.\n1. The 14th element is 6939.\n2. The 15th element is X.\n3. The 16th element is 4461, which needs to be ignored according to instructions, since it's out of range (i~j).\nThe final output should be in reverse order of 6939 -> X -> 4147 = X69394147.
