Insertion sort is a simple sorting algorithm that sorts an array by inserting each element into its proper position in a sorted sequence. 2. The time complexity of insertion sort is O(n^2) in the worst case, where n is the number of elements in the array. 3. Insertion sort is an in-place sorting algorithm, which means it doesn't require any additional memory other than the input array. 4. Insertion sort is stable, which means it preserves the relative order of equal elements. 5. Insertion sort is best suited for small arrays or for arrays that are almost sorted. 6. Insertion sort can be implemented using a nested loop or a recursive algorithm, but the nested loop implementation is more common and more efficient in practice. 7. In Java, the Arrays.sort() method uses a modified version of insertion sort called "binary insertion sort," which uses a binary search to find the correct position for each element instead of comparing it with all the elements to its left. 8. Insertion sort is a good algorithm to teach sorting and for educational purposes because it's easy to understand and implement. ALGORITHM: 1. Start with the second element of the array. 2. Store the second element in a variable called key. 3. Compare key with all the elements to its left (elements 0 to i-1) until you find the correct position for it in the sorted sequence. 4. If an element to the left of key is larger, shift that element one position to the right. 5. Repeat step 4 until you find the correct position for key. 6. Insert key in its correct position in the array. 7. Repeat steps 2-6 for all remaining elements of the array.
