Spy Detected! You are given an array $𝑎$ consisting of $𝑛$ $(𝑛≥3)$ positive integers. It is known that in this array, all the numbers except one are the same (for example, in the array $[4,11,4,4]$ all numbers except one are equal to $4$). Print the index of the element that does not equal others.

WebFor example from test cases where n = 3 and k = 4 so now binary representaion of k is 100. Just take this in base n = 3 so it comes out to be 1*3^2 + 0*3^1 + 0*3^0 = 9 and our answer. Similarly take n = 2 and k = 12. So 12 = 1100 in binary. As our base n is also 2 only answer again converts back to 12. Webgiven an array A[n], its difference array D is some array that satisfies D[i] = A[i] — A[i — 1] (for 1 < i <= N), and D[1] = A[1]. It can be used to perform range update queries of, for instance, adding some value x to all indicies from l to r. you create the difference array, then for each query "l r x", you perform D[l] += x, D[r + 1] -= x, and after all the queries … WebInput. The first line contains a single integer t ( 1 ≤ t ≤ 10 000) — the number of test cases. The first line of each test case contains a single integer n ( 1 ≤ n ≤ 10 5 ). The second line of each test case contains n integers a 1, a 2, …, a n ( 1 ≤ a i ≤ 10 9 ). It is guaranteed that the sum of n over all test cases doesn't ... switch ammp pro hunts
