In our daily life, we have to solve various problems by using different strategies. These strategies are
called problem-solving techniques. A problem-solving technique is a collection of sequential steps to
solve a problem. In the same way, programmers also use different types of techniques to solve the
problems related to programming. Some of these techniques are algorithms and flowcharts.

An algorithm is a set of step-by-step instructions in a sequential manner to solve a problem. A flowchart
is a pictorial representation of an algorithm. A flowchart uses special symbols to represent each step.
An algorithm and a flowchart are the base to write a program. Let us learn more about algorithmic
intelligence and making programs.

ALGORITHM

We know that a program is a collection of instructions. The language used to write a program is called
a programming language. Before writing a program on the computer, every programmer must analyse
the problem and write an algorithm to solve the problem.

An algorithm is a set of steps in a sequential manner to solve a problem or to complete a task. These
steps are the foundation to a program. They are important to programming as recipes are for cooking.
An algorithm is always written in very simple words and precise language so that the steps can be
understood easily by everyone.
