Merge Sort is a divide and conquer algorithm that uses a merge process to merge the two sub-arrays into one by sorting its elements incorrect order. It works on one assumption that the elements in these sub-arrays are already sorted. This is a stable algorithm often used to sort the Linke...
Why to use merge sort?But, the problem with such sorting algorithms like bubble sort, insertion sort, and the selection sort is they take a lot of time to sort.For example, If we have to sort an array of 10 elements then any sorting algorithm can be opted but in case of a...

On the basis of further research in traditional sort merge algorithm,this paper presented an improved algorithm about sort merge join algorithm.This algorithm only performed outer sorting of that little relation and avoided outer sorting of that big relation,so saved a lot of time.At the same tim...
