You are on a planet where chip processing speeds are very slow. A queue is implemented using two stacks, Stack1 and Stack2, and all queue elements must always finally reside in Stack1. The queue currently contains 10 elements in Stack1 and Stack2 is empty. To perform an enqueue operation, you have only push or pop operation that takes 1 second. How much total time (in seconds) is required to perform the enqueue operation?
