Add 1 to the number

Problem to add one to the list.

Example-1:

Input    : n = [ 1, 2, 4]
Output   : [1, 2, 5]

Example-2:

Input    : n = [ 9, 9, 9]
Output   : [1, 0, 0, 0]

Solution

n = [ 1, 2, 4]

a = [str(x) for x in n]

b = "".join(a)

b = int(b)+1

c = [int(y) for y in str(b)]

print(c)

Output

[1, 2, 5]
