Create an algorithm, pseudocode and flowchart for the given questions below: 1. Display all even numbers from 100 to 1. 2. Convert temperature in degree F to Degree C. 3. Output the grade as A, B+, B, C+, C, D+, D, F for the input mark out of 100 (one input and one output) A 90 and above, B+ 85 - 89,8 80-84, C+ 75-79, c 70 - 74, D+ 65-69, D 60 64 and F 0-59. 4. Output the area of a triangle using the relation, Area = S(S-a)(s-b)(S-c), where a, b, c are the three sides of the triangle, S = (a+b+c)/2
