2022. Convert 1D Array Into 2D Array | Python | Fast | Solution | Best | Leetcode 2022

Title: LeetCode 2022 | Convert 1D Array Into 2D Array | Java | Efficient Solution | Best

Description:

Welcome to another coding tutorial! In this video, we solve LeetCode problem 2022, "Convert 1D Array Into 2D Array." This problem involves array manipulation, a fundamental topic for coding interviews and algorithm design.

Problem Description: Given a 1D array original and two integers m and n representing the number of rows and columns, your task is to convert the 1D array into a 2D array with dimensions m x n. If the transformation is not possible, return an empty 2D array.

Example:

vbnet
Copy code
Input: original = [1, 2, 3, 4], m = 2, n = 2
Output: [[1, 2], [3, 4]]
Explanation: The 1D array can be reshaped into a 2D array.

Input: original = [1, 2, 3], m = 1, n = 3
Output: [[1, 2, 3]]
Explanation: The array fits into a single row with 3 columns.

Input: original = [1, 2], m = 1, n = 3
Output: []
Explanation: The transformation is not possible as the array size is insufficient.
In This Tutorial, We Will:

Understand the problem statement and constraints.
Explore the logic behind reshaping arrays and validate input dimensions.
Develop an optimized solution using Java.
Walk through the code step-by-step, ensuring clarity and an efficient approach.
By the end of this video, you will have a solid understanding of how to tackle array manipulation problems like this, making you more confident in technical interviews.
