How Do You Rotate a Matrix 90 Degrees In Place?
To rotate an n x n matrix 90 degrees clockwise in place, first transpose the matrix by swapping element (i, j) with (j, i), then reverse each row, achieving O(…
How Do You Traverse a Matrix in Spiral Order?
Spiral matrix traversal visits every element by tracking four shrinking boundaries — top, bottom, left, right — and walking right across the top row, down the…
