Heap Sort in Java Heap sort is a comparison-based sorting technique which is based on Binary Heap Data Structure. Heap Sort is an optimization of selection sort where we first find the max (or min) element swapping it with the last (or first). and we repeat the same process for the remaining elements. In Heap
Merge Sort in Java The merge sort is a divide and conquer algorithm that divides the input array into equal subarrays and then merges back those subarrays into a sorted array. The process of merge sort is to divide the array into two equal subarrays, sort each subarray, and then merge the sorted subarrays back
Quick Sort in Java Quicksort algorithm is based on the divide and conquer approach where an array is divided into subarrays by selecting a pivot element.The pivot element is positioned in such a way that elements less than pivot are kept on the left side and elements greater than pivot are on the right side.The
Selection Sort in Java Selection Sort is a comparison-based sorting algorithm that sorts an array by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the beginning. The process is continued until the entire array is sorted. Algorithm for Selection Sort Step 1 : Set the first element
