Given a list of numbers, find all pairs of numbers whose sum equals a given target value. For example, given the list [1, 3, 5, 7, 6, 8] and a target of 9, the answer would be (8, 1) and (6, 3).

Iterate through the list and check for pairs that sum up to the target value.

• Iterate through the list and for each element, check if the difference between the target and the element is present in a d...read more
