Asalam O Alikum, welcome to The Academics If you are looking forward for easy access to computer science and other subjects then you are on the right place. The academics is the place where you are going to learn everything in a easy way. Students in this video we are going to cover the following topics:-
Algorithim
24. Define algorithm.
An algorithm is a finite number of steps to solve a problem. The steps given in the algorithm are in a specific order. The steps may consist of input, process, decision and output.
25. Differentiate between flowchart and algorithm. Flowchart uses of standard symbols but algorithm uses of simple English. Flowchart is more time-consuming but algorithm is less time-consuming. Flowchart is difficult to modify but algorithm is easier to modify.
26. What is the role of algorithm in solving a problem?
An algorithm plays an important role in. solving a problem. It is the plan for solving the problem. It helps the user to find the solution of the problem. The process of solving a problem becomes simpler and easier with the help of algorithm.
27. Is it necessary for an algorithm to solve problem in finite number of steps? If yes, why?
Yes, it is necessary for an algorithm to solve problem in finite number of steps. The reason is that the solution of any problem cannot consist of infinite steps. The algorithm has a clear start and end. The solution is found when all steps are performed in a sequence.
28. What is the role of input in the efficiency of an algorithm?
The role of input is very important in the efficiency of an algorithm. An efficient algorithm must clearly define the required Input to solve the problem.
29. What factors are used to measure the efficiency of an algorithm?
The efficiency of an algorithm is measured on the basis of number of steps in algorithm and space in computer memory. An algorithm is more efficient if it takes less number of steps to solve a problem. An algorithm is more efficient if it takes less space in computer memory.
