Add to Array-Form of Integer in Python
Suppose we have a number in array form. So if the number is say 534, then it is stored like [5, 3, 4]. We have to add another value k with the array form of the number. So the final number will be another array of digits.
To solve this, we will follow these steps −
- Take each number and make them string, then concatenate the string
- convert the string into integer, then add the number
- Then convert it into string again, and make an array by taking each digit form the string.
Example
Let us see the following implementation to get better understanding −
class Solution(object):
def addToArrayForm(self, A, K):
num_A = int(''.join(str(i) for i in A))
res = list(str(num_A+K))
res = list(map(int,res))
return res
ob1 = Solution()
print(ob1.addToArrayForm([5,3,4], 78))Input
[5,3,4] 78
Output
[6,1,2]
