Essential Algorithms for programmers
 

Sorting algorithms
An important part of a programmer's success, sorting algorithms include bubble sort, selection sort, and insertion sort. Understanding bubble sort can help programmers develop a foundation for more complex algorithms.
Greedy algorithms
Used to solve optimization problems by choosing the best option at each step, without considering future consequences.
Divide and conquer
A frequently used algorithm that breaks problems into subproblems, solves each one, and then combines the solutions to form the final answer.
Hashing algorithms
Used in cryptography and cyber security to provide unique fingerprints for input data through mathematical functions. Hashing algorithms are important for data integrity, storing passwords, digital signatures, and data indexing.
Backtracking
A fundamental concept that's essential for solving many computer science problems, especially those that are recursive in nature.
Binary search
A crucial concept in programming, especially for those interested in data science and machine learning.
Quick sort
Can be much faster than other algorithms like merge sort and heapsort if implemented properly.
Recursion
Helps programmers break down complex problems into smaller ones, and is used in almost every programming language.
