Question

closest even digits number:

Given an integer N, write a program to print the closest number that has all the even digits. Consider the lowest number if there is same difference between forward and backward numbers.

Input:

The input is a single line containing an integer N.

Output:

The output should be a single line containing the closest integer , that has all even digits.

Explanation:

In the example, the number is 17. The closest number that has all even digits in it is 20. So the output should be 20.

Answer 1

Source code

n=int(input("\nEnter a number: "))


def allEven(list1):
    count=0
    for i in list1:
        if(i%2==0):
            count+=1
    if(count==len(list1)):
        return True
    else:
        return False


while True:
    n_s=[int(i) for i in str(n)]
    if allEven(n_s)==True:
        print("\nClosest even digits number:",n)
        break
    n+=1

Output
