Question

You are provided with 3 numbers : input1, input2 and input3.

Each of these are four digit numbers within the range >=1000 and <=9999

j.e.

1000 <= input1 <= 9999

1000 <= input2 <= 9999

1000 <= input3 <= 9999

You are expected to find the Key using the below formula -

Key = [largest digit in the thousands place of all three numbers] [largest digit in

the hundreds place of all three numbers] [largest digit in the tens place of all

three numbers] [largest digit in the units place of all three numbers]

For e..g. if input1 = 3521. input2=2452. input3=1352, then Key = [3] [5] [5] [2] =

3552

Answer 1

The following cσdes have been written using Python.

input1 = input("Enter a 4-digit number: ")

input2 = input("Enter a 4-digit number: ")

input3 = input("Enter a 4-digit number: ")

print()

ul = list()

tl = list()

hl = list()

thl = list()

ul.append(input1[-1])

tl.append(input1[-2])

hl.append(input1[-3])

thl.append(input1[-4])

ul.append(input2[-1])

tl.append(input2[-2])

hl.append(input2[-3])

thl.append(input2[-4])

ul.append(input3[-1])

tl.append(input3[-2])

hl.append(input3[-3])

thl.append(input3[-4])

um = max(ul)

tm = max(tl)

hm = max(hl)

thm = max(thl)

print(thm + hm + tm + um)

Answer 2

Explanation:

input 1=3521

input 2=2452

input 3=1352

key =[3] [5] [5] [2]=3552
