How does insertion sort work in java

DSA Introduction What is an algorithm? Related Topics Selection Sort Algorithm. Insertion sort works similarly as we sort cards in our hand in a card game. A similar approach is used by insertion sort. Working of Insertion Sort Suppose we need to sort the following array.

Initial array The first element in the array is assumed to be sorted. Take the second element and store it separately in key. Compare key with the first element. If the first element is greater than key , then key is placed in front of the first element.

If the first element is greater than key, then key is placed in front of the first element. Sign Up using. Log In using.
