Along with the array, you are also given a target value k. If you pick up any 2 integers from the array, they would form a pair and have some difference x - y. You need to find out the number of these pairs which have a difference equal to the target difference k. In the above case, you can see a total of 3 pairs which have the target difference of 1. It would look something like: Store the 0th element of the array in a temporary variable. Sorting One common task for computers is to sort data.
