Write a PHP code to find second largest number in array. Given an unsorted array, we have to write a PHP program to find the second largest number in an array.
Apart from solving this problem. We have to focus on time complexity. As the time complexity of an algorithm is very important in terms of how efficient your algorithm is.
In this tutorial, I am going to discuss the implementation of a Binary search using recursion in java.
Given an array of sorted integers and a number k. We have to write a code to search an element k in an array.
For example:
Input: {2, 3, 4, 5, 7, 8}, k = 5
Output: 3 (5 is found at 3rd index)
Input array is sorted and we have to find 5 in this array. The element is found at index 3.
In this tutorial, We are going to learn bubble sort algorithm and it’s implementation in java. We are going to discuss following points in this tutorial.
i) Bubble Sort Algorithm.
ii) Bubble sort program in java (How we can sort an unsorted array using bubble sort algorithm).
iii) Bubble sort video tutorial.
