Manipulating 2D Arrays in CodeHS
In this piece, we will explore how to manipulate 2D arrays in CodeHS, a popular online platform for learning computer science. Specifically, we will focus on the 8.1.5 exercise, which covers various operations that can be performed on 2D arrays.
Then came the test.
First Row Update: Change the final value to the length of the first row. Codehs 8.1.5 Manipulating 2d Arrays
swapColumns(test, 1, 2); System.out.println("\nAfter swapping col 1 and 2:"); print2D(test);What is the specific rule you're trying to implement (e.g., "swap rows" or "change specific characters")? Manipulating 2D Arrays in CodeHS In this piece,
In CodeHS 8.1.5, "Manipulating 2D Arrays," you are tasked with fixing the final element (currently set to 0) of three specific sub-arrays within a 2D array. Objective Summary First Row Update : Change the final value
at the end of each sub-array with values calculated based on different rules for each row. The Core Logic The exercise centers on using a method—often called updateValue —to target a specific index and replace its content. : The final value should be the length of the entire 2D array (the number of rows). : The final value should be the total number of elements across all sub-arrays in the grid. : The final value should be the sum of the first value in row 1 last value in row 3 1. Count All Elements
