Unit 8
My notes on unit 8.
2D Arrays
Arrays inside of arrays aka matrices
When indexing, use row then column.
They are often used to store image data.
Traversal
Have a loop nested inside of another. Outer loop goes through the rows and the inner goes through the columns, or vice verca.
You can use regular for loops or foreach loops, it doesn’t really matter.
Other Notes
For global sorting, make sure to first flatten the array then later to reshape it back.
