# Find Unique Number

## Problem Statement

Given a list or sequence of integer values via the standard input, find the unique number.

Unique number is defined as the number that has all unique digits.

## Input

The first line of input contains a sequence of integer values separated by space.

## Output

Print the unique number of given integer values.

## As is

The boilerplate code is already there to read a sequence of integer values via input from user, in the `main()` function. Also it calls the `findUniqueNumber()` function and prints the returned value. Do not edit this code.

## To do ✍

`findUniqueNumber()` has one parameter: `arr` which is a list of integer values. Write code inside the function body to find the first unique number in the list and return that number.

## Example 1

Test input

``5522 111 32100 22354 128456 2103``

Test output

``128456``

Explanation

• 5522 has the digits 5 and 2 occurring twice. Therefore it is not a Unique number.
• 111 has the digits 1 occurring thrice. Therefore it is not a Unique number.
• 32100 has the digits 0 occurring thrice. Therefore it is not a Unique number.
• 22354 has the digits 2 occurring thrice. Therefore it is not a Unique number.
• 128456 has all unique digits. Therefore it is the Unique number.

## Python Program

``````# Complete the following function
# Return the minimum of given integers in nums
def findUniqueNumber(arr):

# Boilerplate code - Do not edit the following
def main():
arr = [x for x in input().split()]
print(findUniqueNumber(arr))

if __name__ == "__main__":
main()``````

Test case 1

``5522 111 32100 22354 128456 2103``
``128456``

Test case 2

``12356411``
``None``

Test case 3

``122 663 41255 23 0 52155``
``23``
``````# Complete the following function
# Return the minimum of given integers in nums
def findUniqueNumber(arr):
for x in arr:
if len(set(x)) == len(x):
return x
return "None"

# Boilerplate code - Do not edit the following
def main():
arr = [x for x in input().split()]
print(findUniqueNumber(arr))

if __name__ == "__main__":
main()``````
