The combination and use of multiple aspects of knowledge is the main difference between a code farmer and an engineer, and it is also the key to whether to have core competitiveness. Learning knowledge sometimes cannot see how far the road ahead is, but even if it is a mud pit, as long...
() call if any element except the last element is removed (the last element being the element with index: size – 1). Removing the first element means the entire rest of the array is copied which is an O(n) operation. Since the test removes all the elements in the List, the full ...
