In our daily lives, we follow certain steps in a sequential order to perform a task and obtain
the desired output. The word algorithm comes from the name of a Persian mathematician,
Muhammad ibn Musa al-Khwarizmi, who lived in the 9th century. He wrote a famous
book on arithmetic that explained methods of calculation using Hindu-Arabic numerals.
Over time, his name "al-Khwarizmi" was Latinized to "Algoritmi," and from this the term
algorithm was born. In the beginning, algorithms were mainly used in mathematics
for solving equations and performing calculations. Later, with the development of
computers in the 20th century, algorithms became the foundation of computer science.
Today, algorithms are used everywhere from solving complex problems in technology to
performing simple tasks in our daily lives.
Algorithm
An algorithm is a set of step-by-step instructions used to solve any logical or mathematical
problem. It is always written in a simple, clear, and precise manner so that anyone can
easily understand and follow the steps.
Features of Algorithm
1. It has a fixed number of steps.
2. Each step is clear and exact.
3. Steps are followed in order.
4. It takes some input.
5. It gives an output.
6. It is simple to understand.
7. Every step is useful.
8. It can be used for similar problems.
