apcsaArraysSwapLeastTwoToFront
This function returns the input array (or a copy of the input array) where the first element has been swapped with the least element, and the second element has been swapped with the second-least element. If the first and second elements are the least and second-least elements, the array is returned unchanged. HINTThe most common algorithm here will come to you after you reflect on the following: what does the array look like after you find and swap the first and least elements? In other words, once the element at index 0 is guaranteed to be the least element, which elements of the array do you really need to think about when finding the second-least element? apcsaArraysSwapLeastTwoToFront([0, 1, 2, 3]) → [0, 1, 2, 3] apcsaArraysSwapLeastTwoToFront([-1, -3, -5]) → [-5, -3, -1] apcsaArraysSwapLeastTwoToFront([0, -1]) → [-1, 0] ...Save, Compile, Run (ctrl-enter) |
