Solution: Add to Array-Form of Integer
Explore how to add a given integer to a number represented by an array of its digits. Understand the step-by-step process of simulating manual addition digit by digit, handling carry propagation efficiently, and returning the final sum as an array. This lesson helps you practice mathematical problem-solving with arrays and offers insight into time and space complexity considerations.
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.
