How Does the Next Permutation Algorithm Work?
The next permutation algorithm rearranges a sequence in place into the lexicographically next greater permutation using O(n) time and O(1) extra space, by find…
How Do You Rotate an Array by K Positions?
The optimal way to rotate an array of n elements right by k positions in place is the three-reversal trick: reverse the whole array, then reverse the first k e…
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(…
What is the Fisher-Yates Shuffle Algorithm?
The Fisher-Yates shuffle is an in-place algorithm that produces a uniformly random permutation of an array in O(n) time by iterating from the last index to the…
In-Place vs Out-of-Place Algorithms: What is the Difference?
An in-place algorithm transforms its input using only O(1) or O(log n) extra memory beyond the input itself, typically by overwriting the input structure direc…
