# Top 8 Algorithms Every Programmer Should Learn A set of instructions that can be used to solve a mathematical problem or perform a calculation is an algorithm. It is a collection of instructions that, when implemented into a software or hardware-based process, perform the predetermined activities step-by-step.

In mathematics and computer sciences, “algorithms” are usually short methods used to solve a problem that occurs repeatedly. Here are eight common types of algorithms for you. Have a look.

## Top 8 Algorithms Every Programmer Should Learn

### 1. Sorting Algorithms

Sorting is an essential activity in computer sciences, and there are many effective algorithms to accomplish this task. These algorithms include quicksort, merg sort, and heap sort.

## 2. Search Algorithms

Searching for an element within a large dataset is a common task. There are many algorithms that can be used to do this, including binary search and hash tables. It is common to search for an element within a large dataset.

### 3. Graph Algorithms

Graph algorithms can be used to solve problems relating to graphs. For example, they can identify whether a graph has links or find the shortest path between two nodes. Finding the shortest route between two nodes is one example of a problem that can be solved by graph algorithms.

### 4. Dynamic Programming

Dynamic programming is the process of resolving problems by first breaking them down into smaller subproblems. Then, you can store the answers for these subproblems to avoid having to do calculations more than once.

### 5. Greedy Algorithms

In order to solve optimization issues, greedy algorithms select the local optimal option at each step in the process with the hope of finding the global optimal option.

### 6. Divide and Conquer

A paradigm for building algorithms known as “divide-and-conquer,” is a recursion with multiple branches. The “divide-and-conquer” method breaks down a complicated issue into smaller ones of the same type or similarity and then simplifies them until they are resolved.

### 7. Backtracking

Backtracking is an algorithmic technique that abandons a path when it determines it can’t be part of the answer. Backtracking is a systematic search of all possible combinations and it abandons a route as soon as it determines it can’t be part of the solution.

### 8. Randomized Algorithm

Randomized algorithms use the chance to solve problems, rather than predetermined patterns. You can use it to either increase the complexity of an average problem or solve problems that are impossible to solve deterministically. These two applications are both valuable.
