Solution: Add to Array-Form of Integer
Explore how to add an integer k to an array-form integer using a digit-by-digit addition approach that treats k as a carry. Understand the step-by-step algorithm to update digits and handle carries without converting the array to an integer. This lesson helps you implement an efficient solution with clear time and space complexity insights.
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.
