Sorting algorithms are a set of instructions that can be used to arrange a collection of items in a specific order. There are many different sorting algorithms, each with their own strengths and weaknesses.

Searching algorithms are methods used to locate a specific element within a collection of data. The efficiency of a searching algorithm depends on the size of the collection and the number of elements that must be searched. There are several types of searching algorithms, including linear search, binary search, and hash table search. Overall, the… Continue reading Searching Algorithms

An array is a data structure that stores a collection of elements, each identified by an index or a key. The elements can be of any data type, such as integers, floating-point numbers, strings, or objects. The size of an array is fixed at the time of its creation and cannot be changed afterward.

Complexity analysis of data structures and algorithms refers to the process of determining the computational complexity of a given algorithm or data structure. It is a way to measure the performance of an algorithm or data structure in terms of the amount of resources (such as time and space) it requires to complete its task. The two main metrics used in complexity analysis are time complexity and space complexity.
