Given an input array of integers, your goal is to find the second biggest element present in the array in an effective way. Note, you need to achieve this in O(n) time i.e., you should be able to find result… Read More!
In our Java program below we use insertion sort to sort Student objects based on the lastName key values. The doInsertionSort() method in this example is similar to doInsertionSort() method in the insertion sort example, but the only difference is we… Read More!
Selection sort is a sorting algorithm, precisely an in-place comparison sort. The selection sort improves over the bubble sort by reducing the number of swapping necessary from O(n2) to O(n). But the number of comparisons remains O(n2). Selection Sort Java… Read More!
Bubble Sort is a simple sorting algorithm that repeatedly steps through the list to be sorted and compares each pair of adjacent elements in the list and swaps them if they are not in order. This algorithm is too slow… Read More!
Binary search is also known as half-interval search or logarithmic search. It is a searching algorithm used to find the position of an element in the sorted array. The payoff for using a sorted array comes when we use a… Read More!
