## Integer and Float Number

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.

## Model solution

• h = int(input())
• m = int(input())
• s = int(input())
• print(h * 30 + m * 30 / 60 + s * 30 / 3600)

OR
• # hour = int(input("Input: "))
• # minute = int(input("Input: "))
• # second = int(input("Input: "))
• # print((hour*3600 + minute*60 + second)/120)
