Q.1.

An algorithm is a step by step solution to a given problem.

Read all FOUR steps of an algorithm and draw a flowchart for it.

1.Assign the value 0 to the variables SUM and N respectively.

2.Apply an increment on N by 1 and store the new value back in variable N.

3.Add the values of SUM and N. Store the result back in SUM variable.

4.If the value of N is equal to 50, then print the value of SUM otherwise repeat the steps 2, 3 and 4 until the value of N is equal to 50.

(Note: Use the same variable names in flowchart that are given in the algorithm.)
