What is a Nxn spiral?

An n x n matrix has ceil(n/2) square cycles. A cycle is formed by ith row, (n-i+1)th column, (n-i+1)th row and ith column where i varies from 1 to ceil(n/2). 25 24 23 22 21 10 9 8 7 20 11 2 1 6 19 12 3 4 5 18 13 14 15 16 17.

How do you traverse a matrix?

Two common ways of traversing a matrix are row-major-order and column-major-order. Row Major Order : When matrix is accessed row by row. Column Major Order : When matrix is accessed column by column. Recommended: Please try your approach on {IDE} first, before moving on to the solution.

How does a spiral matrix work?

How does the spiral matrix algorithm work? The algorithm starts from the top left corner of the array, and traverses the first row from left to right. Once it traverses the whole row it does not need to revisit it, thus, it increments the top corner index. Once complete, it traverses the rightmost column top to bottom.

How do you traverse a 2d matrix?

You can think about a two-dimensional array as a matrix that has rows and columns, this helps to visualize the contents of an array. In order to loop over a 2D array, we first go through each row, and then again we go through each column in every row. That’s why we need two loops, nested in each other.
