A sorting algorithm is a method for reorganizing a large number of items into a specific order, such as alphabetical, highesttolowest value or shortesttolongest distance.
If the data is unevenly distributed, then some of the intermediate bins can be empty. This algorithm is not suitable for large data sets as its average and worst case complexity are of. But in quick sort all the heavy lifting major work is done while dividing the array into subarrays, while in case of merge sort, all the real work happens during merging the subarrays. The process of sorting based on the concept of divide and conquer is merge sort. Quick sort is also based on the concept of divide and conquer, just like merge sort.

When goods are placed into storage, the system selects coordinates in ascending order according to specific sort criteria, and assigns the next available storage bin based on the coordinate structure you define for creating bins. After this code does its job, the value of a would be 35 and the value of b would be 25 so in the exchange function above, if we have two different array elements at positions m and n, we are basically getting each value at these positions, e. The selection sort algorithm in data structures for sorting a works as follows pass 1. The elements are assigned to the bins based on the computations performed on each element.
