Write c++ code to solve the following problem: Given an array of n integers, find the first element that occurs k number of times. If no element occurs k times, print -1. Use a map to solve the problem. Examples: Input: (1, 7, 4, 3, 4, 8, 7) and k = 2 Output: 4 Input: (4, 1, 6, 1, 6, 4) and k = 1 Output: -1 Explanation: Both 7 and 4 occur 2 times, but 4 Explanation: No element occurs 1 time is the first that occurs 2 times.
