Finally, the last method to find duplicates in an array is to use the for loop.Here is an example that compares each element of the array with all other elements of the array to check if two values are the same using nested for loop:...
given an array that contains duplicates (except one value), find the one value that does not have a duplicate in that array. Explain the complexity of your algorithm. So in the array: A = [2, 3, 4, 5, 2, 3, 4] your algorithm should return 5 since that's the value that does n...
