Find Key 1 – Wipro Sample Coding Question Solved – codewindow.in

/ Wipro Coding Questions / By Coder_Shark

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 = [LARGEST digit in the thousands place of all three numbers – smallest digit in the thousands place of all three numbers] [LARGEST digit in the hundreds place of all three numbers – smallest digit in the hundreds place of all three numbers] [Largest digit in the tens place of all three numbers – smallest digit in the tens place of all three numbers] [LARGEST digit in the units place of all three numbers – smallest digit in the units place of all three numbers]

Solution 1

Solution 2

For Example
If input1 = 3521,input2 = 2452, input3 = 1352,
Then key = [3-1][5-3][5-2][2-1] = 2231
Assuming that the 3 numbers are passed to the given function, Complete the find and return the Key.
