Study Notes
Space Complexity Categories
-
O(1) - Constant Space: The algorithm uses a fixed amount of extra space, independent of the input size. Examples include modifying data in place.
-
O(n) - Linear Space: The space requirement increases proportionally to the input size. An example is copying input data to a new list.
-
O(n^2) - Quadratic Space: The space grows with the square of the input size. A 2D array of dimension n x n exemplifies this.
-
O(log n) - Logarithmic Space: Space usage increases slowly, proportionally to the logarithm of the input size. This is common in algorithms like binary search due to the divide-and-conquer nature.
-
O(n log n) - Linearithmic Space: Space usage increases proportionally to the input size multiplied by its logarithm. Common in some sorting algorithms (like merge sort) due to both input handling and temporary storage.
-
O(2^n) - Exponential Space: This describes algorithms requiring an enormous amount of space that grows exponentially with the input size. Brute-force solutions to problems like the Traveling Salesman Problem often exhibit this. Recursive Fibonacci calculation storing all preceding values also demonstrates exponential space.
