Integer and Float Number

Useful Links:

1) Last digit of integer

Statement

Given an integer number, print its last digit.

Model solution

a = int(input())
print(a % 10)

2) Tens digit

Statement

Given an integer. Print its tens digit.

Model solution

n = int(input())
print(n // 10 % 10)

3) Sum of digits

Statement

Given a three-digit number. Find the sum of its digits.

Model solution

n = int(input())
a = n // 100
b = n // 10 % 10
c = n % 10
print(a + b + c)

4) Fractional part

Statement

Given a positive real number, print its fractional part.

Model solution

x = float(input())
print(x - int(x))

OR

# num = float(input("Enter the number: "))
# real = num - int(num)
# frac = str(round(real, 3))
# print(frac)

5) First digit after decimal point

Statement

Given a positive real number, print its first digit to the right of the decimal point.

Model solution

x = float(input())
print(int(x * 10) % 10)

OR

# num = float(input("Enter the Number: "))
# rd = int(num*10)
# print(rd % 10)

6) Car route

Statement

A car can cover distance of N kilometers per day. How many days will it take to cover a route of length M kilometers? The program gets two numbers: N and M.

Model solution

from math import ceil
n = int(input())
m = int(input())
print(ceil(m / n))

OR

# n = int(input("Input: "))
# m = int(input("Input: "))
# perday = m/n
# day = ceil(perday)
# print(day)

7) Digital clock

Statement

Given the integer N - the number of minutes that is passed since midnight - how many hours and minutes are displayed on the 24h digital clock?

The program should print two numbers: the number of hours (between 0 and 23) and the number of minutes (between 0 and 59).

For example, if N = 150, then 150 minutes have passed since midnight - i.e. now is 2:30 am. So, the program should print 2 30.

Model solution

n = int(input())
hours = n // 60
minutes = n % 60
print(hours, minutes)

8) Total cost

Statement

A cupcake costs A dollars and B cents. Determine, how many dollars and cents should one pay for N cupcakes. A program gets three numbers: A, B, N. It should print two numbers: total cost in dollars and cents.

Model solution

a = int(input())
b = int(input())
n = int(input())
cost = n * (100 * a + b)
print(cost // 100, cost % 100)

9) Clock face - 1

Statement

H hours, M minutes and S seconds are passed since the midnight (0 ≤ H < 12, 0 ≤ M < 60, 0 ≤ S < 60). Determine the angle (in degrees) of the hour hand on the clock face right now.
