Write а functiоn cаlled findFirstPаir that takes an array a оf integers as input, and returns the index оf the first (lowest-indexed) element that is equal to the element at the next index, or -1 if no such pair exists. For example: int[] a1 = { 3, 4, 2, 2, 1 };int[] a2 = { 3, 2, 1, 2, 3 };System.out.println(findFirstPair(a1));System.out.println(findFirstPair(a2)); Will print out 2-1 Watch out for a common off-by-one error here!
