In programming, algorithms are the backbone of software development, as they break down operations into steps that make it much easier to achieve a specific result.
What is the algorithm? What are the rules features and benefits of the algorithm?
The method by which a problem is solved step by step is called an algorithm. An algorithm means step-by-step problem-solving.
Example:Write the algorithm to find the sum of three numbers.
Step 1: Start.
Step 2: Take three numbers.
Step 3: Add the three numbers.
Step 4: Displaying the sum.
Step 5: Finish.
Type of Algorithm:
Algorithms can be classified into different types based on their design and functionality. Popular types among them are:
1. Sorting Algorithm.
A sorting algorithm is a process that arranges data or elements in a specific order according to certain criteria. For example, arranging numbers or words in ascending or descending order. Bubble Sort, Quick Sort, and Merge Sort are the best-known and most used sorting algorithms. These algorithms are very important in data management and organization.
2. Search Algorithm.
A search algorithm is a process by which a specific value is found within a given data set or list. For example, finding a specific number or word in a list. Among the search algorithms, Linear Search and Binary Search are widely used. They are used a lot in data retrieval and data search.
3. Recursive Algorithm.
An iterative algorithm is a process in which a function or method repeatedly calls itself to solve a problem. It usually solves large and complex problems by breaking them down into smaller subproblems. For example, iterative algorithms are used to solve the factorial, Fibonacci series, and Tower of Hanoi problems. These algorithms are very effective in reducing the complexity of the problem.
Rules and Features of Algorithm:
1. Algorithms written should be straightforward.
2. Each step should be clear so that Genco programmers can easily understand it.
3. Solve the problem step by step.
4. It should be widely applicable. That is, many problems can be solved with this same algorithm.
Algorithm Advantages:
1. Helps to easily understand the solving way of the program. That is, the algorithm is written as if it were designed to solve a problem easily.
2. Helps in diagnosing programmer errors. If the program does not match the algorithm, mistakes can be easily found.
3. Assists in program modification and enhancement.
4. A complex program can be written very simply with algorithms.
An example of the algorithm to find the area of a triangle:
Step 1: Start.Step 2: Take the area and height of the triangle.
Step 3: Area = 1/2 * area * height, using this formula to find the area of the triangle.
Step 4: Showing the area of the triangle.
Step 5: Finish.
Importance of Algorithms in Programming.
Algorithms are very important in programming as they make code simple, efficient, and performant. Well-designed algorithms significantly reduce project execution time and resource consumption. This makes them important for developing high-performance applications, especially in data processing, machine learning, and artificial intelligence. Algorithms use data to better figure out solutions to problems.
Another example of an algorithm:
Write the algorithm to find the larger number between 2 integers.
Step 1: Start.
Step 2: Take the number 2.
Step 3: Is the 1st greater than the 2nd?
a) Yes, the 1st digit printed in the result is larger.
b) No, the 2nd number printed in the result is larger.
Step 4: Finish.
