Merge Sort
Consider the problem of sorting an array of numbers in order. Merge sort is to recursively divide the array in half, and then recombine the sorted subarrays. Divide the array in half. Recursively divide until each subarray has only one …
Selection, Insertion and Bubble Sort
Sorting — arranging items in order — is the most fundamental task in computation. Sorting enables efficient searching algorithms such as binary search. Selection, insertion and bubble sort are easily understandable and also similar to each other, but they are …
Algorithm Analysis
Binary search looks more efficient than linear search when the array is sorted. The efficiency (time complexity) of an algorithm can be measured by the running time as a function of the input data size. Such functions are called growth …
