Code for Addition Program

# Python
a, b = int(input()), int(input())
print(a + b)

Some question, there may be a template for you. Copy and paste it, then write your code in there.

1. (5 pts) Warm-up

Write a program that takes 2 non-negative floating-point numbers as inputs: m and n.

The program shall output sum, absolute difference, product, mean, maximum, and minimum of those values. Round them to 2 decimal places

Input (Each Line)

1. Integer m
2. Integer n

Output (Each Line)

1. Sum of m and n
2. Absolute Difference of m and n
3. Product of m and n
4. Mean of m and n
5. Maximum of m and n
6. Minimum of m and n

Example 1

--- Input ----
4
10
--- Output ---
14.0
6.0
40.0
7.0
10.0
4.0

2. (5 pts) Prime

A prime number p is a number that only p and 1 can divide while p > 1. Write a program that check if the integer that user inputs is a prime or not. If p is prime, the program should output PRIME, otherwise NOT PRIME.

There are many methods to check whether the number is prime.

Input (Each Line)

1. Integer p

Output (Each Line)

1. PRIME or NOT PRIME

Example 1

--- Input ----
9
--- Output ---
NOT PRIME

Example 2

--- Input ----
17
--- Output ---
PRIME

3. (5 pts) Odds, Evens

Write a function that returns 2 numbers: how many odds and how many evens are there in the list. The function takes a list x as an input and returns a and b.

Note that a function can return multiple values, and you can index them.

Template (Copy and paste)

# Template for Q1A 3
# Do not change anything else!

def count(x):
    a, b = 0, 0
    
    # write your code here
    
    return a, b

exec(input().strip())

Example 1

--- Input ----
print(count([1, 3, 7, 9, 10, 2, 6, 3, 5, 7, 7, 9, 99]))
--- Output ---
(10, 3)

Example 2

--- Input ----
print(count([]))
--- Output ---
(0, 0)

4. (5 pts) Circular List

A circular list is a list that the index runs in circle. For an ordinary list of length 10, you can index them from 0 to 9. A circular list, on the other hand, can be indexed with any non-negative numbers.

For example, we have a circular list q = [0, 1, 2, 3] of length 4. If we index them, we should get the following:

q[0] -> 0
q[1] -> 1
q[2] -> 2
q[3] -> 3
q[4] -> 0
q[5] -> 1
q[6] -> 2
...
q[61] -> 1
...

Circular Buffer (Ring Buffer) of size 16

How can we achieve this behavior? Write a function that takes 2 inputs: a list q and an index i. The output should mimic q[i] as said above. The list q is guaranteed to have at least 1 element.

Template (Copy and paste)

# Template for Q1A 4
# Do not change anything else!

def index(q, i):
    # write your code here
    # This function should return something.

exec(input().strip())

Example 1

--- Input ----
print(index([6, 9, 1, 2, 5, 7], 3))
--- Output ---
2

Example 2

--- Input ----
print(index([6, 9, 1, 2, 5, 7], 10))
--- Output ---
5

Example 3

--- Input ----
print(index([30], 9999999999))
--- Output ---
30

5. (10 pts) Time Difference

A point of time consists of hour: h, minute: m, and second: s.

Write a program that calculate the difference of time in this format.

The user should input h1, m1, s1 and h2, m2, s2

The program should output time difference in h m s format.

Conditions

• Time difference is absolute.
• 0 <= h <= 24
• 0 <= m, s <= 60

Template (Copy and paste)

# Template for Q1A 5
# Do not change anything else!

h1, m1, s1 = input().strip().split()
h2, m2, s2 = input().strip().split()

h1, m1, s1 = int(h1), int(m1), int(s1)
h2, m2, s2 = int(h2), int(m2), int(s2)

# write your code here
# Should print something.

Input (Each Line)

1. Integers h1 m1 s1
2. Integers h2 m2 s2

Output (Each Line)

1. Time Difference in h m s format. See examples for more details.

Example 1

--- Input ----
24 00 50
24 00 30
--- Output ---
0 0 20

Example 2

--- Input ----
24 30 50
24 20 00
--- Output ---
0 10 50
