Checking an Array for Duplicate Values

Problem Statement We have to implement a function containsDuplicate() that takes an integer array as input and returns true if an element occurs more than once and false otherwise. Brute Force Solution The simplest solution for this problem would be two nested loops, where the first loop will select an element and the second loop will select another element from the array and compare them.

Arrays, Strings, and HashMaps

Data structures like arrays, strings, and hashmaps are available by default in most programming languages. They facilitate storage of large amounts of data in an efficient format which makes it easier (and sometimes relatively faster) to access during runtime. Arrays An array is a sequential store of data (referred to as elements). In languages like Python, an array can store elements with multiple data types, like, [1, "Hello, World", True] but for languages like Go, C++, and Java an array can store elements of a singular data type....
