Heap sort algorithm Heap sort was invented by John Williams. Heap is a complete binary tree in which every parent node be either greater or lesser than its child nodes. Heap sort is a comparison based sorting technique based on Binary Heap data structure. It is similar to selection sort where we first find the maximum element … Read more
Quick Sort Algorithm There are may versions of Quick sort, which is one of the most popular sorting methods due to its speed (O(N lgN) average, but O(N^2) worst case). Here’s the steps to follow: Pick a “pivot” item Partition the other items by adding them to a “less than pivot” sublist, or “greater than … Read more
Merge Sort Algorithm Merge Sort is a Divide and Conquer algorithm. It divides input array in two halves, calls itself for the two halves and then merges the two sorted halves. The merge() function is used for merging two halves. The merge(arr, l, m, r) is key process that assumes that arr[l..m] and arr[m+1..r] are sorted and merges … Read more
Matrix multiplication program in C Matrix multiplication in C language to calculate the product of two matrices (two-dimensional arrays). A user inputs the orders and elements of the matrices. If the multiplication isn’t possible, an error message is displayed. You may have studied the method to multiply matrices in Mathematics. Matrix multiplication in C language … Read more
