## Linear Search vs Binary Search

Earlier we have seen linear search and binary search and how these work individually, In this article we will compare these two search algorithms. If you are new to these, please read the prerequisites...

Objective: Given an array of integers, write an algorithm to find the third largest element in the array. Example: Int [] a = { 6, 8, 1, 9, 2, 1, 10} Output: Third largest...

Objective: Given an array of integers that contains duplicates as well. Write a program to find the sum of all unique elements in the array. This problem is also referred to as find the...

Objective– Given an array of numbers, write a java program to find the largest element in the given array. Example: int [] a = {1, 5, 3, 9, 2, 8, 2} Largest Element: 9...

Objective: Given an array of integers, write an algorithm to find the three smallest elements in the array. Example: Int [] a = { 6, 8, 1, 9, 2, 10}; Output: 1, 2, 6...

Earlier we saw about Stack and its implementation using Linked List. Java has a built in class for Stack. In this article we will discuss about it in detail. First brief about Stack. What...

Objective: Given an array of integers, write a program to check if array contains all unique numbers. Example: Integer [] arrA = { 1, 2, 3, 6, 4, 9, 8}; Output: Array has all...

Objective: Given an array of integers which contains duplicates as well. Write a program to find the product of all unique elements in the array. This problem is also referred as find the product...

Objective: Given an array of integers, write an algorithm to find the two smallest elements in the array. Example: Int [] a = { 6, 8, 1, 9, 2, 10}; Output: 1, 2 Int...

Objective: Given an unsorted array of numbers and a number ‘x’, write a java program to search the number ‘x’ in the array and return its index else return -1. Example: Int [] a...

Objective: Given an array of integers which contains duplicates as well. Write a program to print all unique elements in the array. This problem is also referred as print all distinct elements in the...

Objective: Given an array of integers A[],find no of reverse pairs means no of (i, j) pairs where i < j and A[i]>A[j]. Example: A[] = {10, 3, 4, 2, 5, 7, 9, 11}...
