Given a number N, the task is to find the smallest Even number with N digits.
Input: N = 1 Output: 0 Input: N = 2 Output: 10
Case 1 : If N = 1 then answer will be 0.
Case 2 : if N != 1 then answer will be (10^(N-1)) because the series of smallest even numbers will go on like, 0, 10, 100, 1000, 10000, 100000, …..
Below is the implementation of the above approach:
# Python3 implementation of
# the approach
# Function to return smallest
# even number with n digits
def smallestEven(n) :
if (n == 1):
return pow(10, n – 1)
# Driver Code
n = 4
