Q. Is there a more efficient sorting algorithm than bubble sorting? A. Although bubble-sort is one of the simplest sorting algorithms, it’s also one of the slowest. It has the O(n2) time complexity. Faster algorithms include quick-sort and heap-sort. The Arrays.sort( ) method uses the quick-sort algorithm, … Read more...

Q. You need to sort an array of integers by repeatedly reversing the order of the first several elements of it. you always have to flip from the beginning element, you cannot flip elements 2 and 3. For example, input: [10,30,20] [10,30,20] –> 2 moves reversing 10 & … Read...
