Find Key 2 – Wipro Sample Coding Question Solved – codewindow.in

You are provided with 3 numbers: input1, input2 and input3.
Each of these are four digit numbers within the range >= 1000 and <= 9999, i.e.
1000 <= input1 <= 9999
1000 <= input2 <= 9999
1000 <= input3 <= 9999
You are expected to find the key using the below formula:
Key = (Sum of Smallest digits of all the 3 numbers) – (Sum of Largest digits of all the 3 numbers)
For Example
if input1 = 3521, input2 = 2452, input3 = 1352, then key = (1+2+1) – (5+5+5) = -11
Assuming that the 3 numbers are passed to the given function, Complete the function to find and return the Key.
