1. Write algorthim/pseudocode for a program that assigns a letter grade for an inputted quiz score, according to the following table: 4 pts

Score	Grade
90-100	A
80-89	B
70-79	C
60-69	D
< 60	F

The program accepts the score and then displays the Grade for that score.

3. Write a program that reads an integer and prints how many digits the number has, by checking whether the number is <10, <100, and so on. (Assume that all integers are less than ten billion.) If the number is negative, first multiply it by -1. DO NOT use the len function. 6 pts

a) Your code with comments

Test Cases:

20 (should print 2 digits)

-89654 (should print 5 digits)

9000000000 (should print 10 digits)

4. Write a program that reads three numbers and prints all the same if they are all the same, all different if they are all different, and neither otherwise. 5 pts

a) Your code with comments

Test Cases:

1 1 1 (should print all the same)

1 2 3 (should print all are different)

1 1 2 (should print neither)

5. When two points in time are compared, each given as hours (in military time, ranging from 0 to 23) and minutes, the following pseudocode determines which comes first. 5 pts

If hour1 < hour2

time 1 comes first

Else if hour 1 and hour 2 are the same

If minute 1 < minute 2

time 1 comes first.

Else if minute 1 and minute 2 are the same

time 1 and time 2 are the same.

Else

time 2 comes first

Else

time 2 comes first.

Write a program that prompts the user for two points in time (hours and minutes) and prints the time that comes first, then the other time.

a) Your code with comments

Test Cases:

14:12 16:30 (should print Time 1 comes first)

15:35 15:11 (should print Time 2 comes first)

20:23 8:15 (should print Time 2 comes first)

6. Write a program that reads in three strings and sorts them lexicographically. Do NOT user the sort function. 5 pts

Enter string 1: Charlie

Enter string 2: Able

Enter string 3: Baker

Able

Baker

Charlie

a) Your code with comments

Test Cases:

Able, Baker, Charlie

Baker, Charlie, Able

Charlie, Able, Baker

Able, Charlie, Baker

Baker, Able, Charlie

Charlie, Baker, Able
