It determines that what we have to perform and in which order for completing the required task properly. The major problem that has to solve is broken down into sub problems and organized such that it will resolve the problem successfully.
In our daily life algorithm plays an important role. As we plan our daily works such that what we have to do, at what time and in which order.
For instance a student plans that:
1. It will wake up at 8:00 am
2. have his/her breakfast at 8:15 am
3. go to school at 8:30 am
4. then comes back from school at 1:00 pm
5. have rest etc
Student plans all these tasks in an order to manage the daily routine.
Thus, orderly management of a work is said to be an algorithm in general sense and all of us use it in our lives to some extent.
