Approaches in Dynamic Programming

In this blog post, we'll explore the approaches used in Dynamic Programming (DP), a powerful technique for solving complex problems by breaking them down into simpler subproblems. You'll learn about the two main approaches—Top-Down and Bottom-Up—how they work, their pros and cons, and examples to illustrate their application.

Arrays - Bubble Sort in DSA

Bubble Sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted. The algorithm, which is a comparison sort, is named for the way smaller elements 'bubble' to the top of the list. Although the algorithm is simple, it is too slow and impractical for most problems even when compared to insertion sort. It can be practical if the input is usually in sort order but may occasionally have some out-of-order elements nearly in position.

Arrays - Insertion Sort

Insertion Sort is a simple sorting algorithm that builds the final sorted array one item at a time. It is much less efficient on large lists than more advanced algorithms such as quicksort, heapsort, or merge sort.

Arrays - Selection Sort in DSA

Selection Sort is an in-place comparison sorting algorithm that divides the input list into two parts: the sublist of items already sorted and the sublist of items remaining to be sorted. It repeatedly finds the minimum element from the unsorted part and puts it at the beginning of the unsorted part. The algorithm maintains two subarrays in a given array. The subarray which is already sorted and the remaining subarray which is unsorted. In every iteration of selection sort, the minimum element from the unsorted subarray is picked and moved to the sorted subarray.

Arrays in Data Structures and Algorithms

An array is a collection of items stored at contiguous memory locations. It is a data structure that stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

Circular Queue Data Structure

A circular queue is a linear data structure that operates on the First In First Out (FIFO) principle but utilizes a circular arrangement for its storage. This allows for efficient use of space and reduces the overhead associated with traditional linear queues.

Iterative Binary Search

In this blog post, we'll explore the iterative binary search algorithm, a fundamental technique in computer science for efficiently finding an element in a sorted array.

By the end, you'll have a thorough understanding of iterative binary search and how to implement it in your programming projects.

Priority Queue Data Structure

A priority queue is an abstract data type similar to a regular queue or stack data structure, but with an added feature that allows each element to have a priority. In a priority queue, elements are served based on their priority rather than their order in the queue.

By the end, you'll have a thorough understanding of recursive binary search and how to implement it in your programming projects.

Space Complexity

Space complexity is a measure of the amount of working storage an algorithm needs. It is a measure of the amount of memory space an algorithm needs to solve a problem as a function of the size of the input to the problem. It is the amount of memory space required by the algorithm to execute in its life cycle.

Stack Data Structure

A stack is a linear data structure that follows the Last In First Out (LIFO) principle. It allows operations to be performed at one end, called the top of the stack, making it efficient for scenarios such as expression evaluation, backtracking algorithms, and function call management.

Time Complexity

Time Complexity is a measure of the amount of time an algorithm takes to solve a problem as a function of the size of the input to the problem. It is commonly estimated by counting the number of elementary operations performed by the algorithm, where an elementary operation takes a fixed amount of time to perform.
