Instructions: Program and solve the following tasks in a script file; publish it as a PDF and submit it on Blackboard in the content section. Ensure that you put the proper header information $($your name, course name, date, HW number, etc.$)$ as shown in the class. Divide the script into sections for each task.

Task $1$:

Write a program that accepts a numerical value $x$ from $0$ to $100$ as input and computes and displays the corresponding letter grade given by the following table.

A $x90$

B $80x89$

C $70x79$

D $60x69$

F $x<mn>6</mn><mn>0</mn>$

Use the ranges, i$.$e$.,$ starting and ending points for all grades. When assigning a letter grade, ensure that you use the single quotes for the letters like this: lettergrade $=\text{'}$ A $\text{'}.$ Test the program for numericalgrade $=55.$ Hint below:Task $2$:Randomize the sequence of your conditional branches of Task $1$ and run the script. Comment "Yes$/$No$"$ at the bottom of your script if the sequence of the branches affects the output or not i$.$e$.,$ if I put the condition for A at the bottom and the condition for D at the top, and the condition for C before B etc. Test the program for numericalgrade $=87.$

Task $3$:

Solve Task $1$ in sequential order $($A$,$ B$,$ C$...)$ but without the upper bounds of the numerical ranges, i$.$e$.,$ only utilize the conditions similar to "numericalgrade $70,$ numericalgrade $90",$ etc. Test the program for numericalgrade $=63.$

Task $4$:

Randomize the sequence of your conditional branches of Task $3$ and run the script. Comment "Yes$/$No$"$ at the bottom of your script if the sequence of the branches affects the output or not. Test the program for numericalgrade $=105.$
