Solution: Add to Array-Form of Integer
Explore how to compute the sum of an integer represented as an array of digits and an integer k by performing right-to-left addition with carries. Understand the step-by-step method to handle digit addition without converting the entire array to an integer, and learn to implement this with optimal time and space complexity.
We'll cover the following...
Statement
The array form of an integer is defined as an array of its digits ordered from left to right. For instance, the array form of [1, 3, 2, 1].
You are given num, which represents an integer in its array form, and an integer k. Compute the sum of the integer represented by num and k, then return the result as an array form representation.
Note:
numwill not contain leading zeros unless the number itself is zero.
