Analyzing runtime Insert element into position 0 of an array of size n (in java) correct answers Runs in linear time, (if the array is size n and you double it, time will be doubles as well, this is a good way to think about linear time). Analyzing runtime Retrieving an element from an array of size n (at a particular index, in java). correct answers When the CPU has to do the arithmetic to get the element from the specified index, it's a constant time operation. The arithmetic barle...
