Algorithm tools help you learn and verify computer science fundamentals interactively. Watch sorting algorithms animate step by step, convert numbers between binary, decimal, hex, and octal, compute bitwise AND/OR/XOR with a visual bit grid, and generate truth tables from logical expressions — all free in the browser.
Built for CS students, interview prep, and curious developers, this cluster makes abstract concepts concrete. The Sorting Visualizer animates bubble, selection, insertion, merge, and quick sort with bar charts; the Binary/Hex Converter live-syncs all four number bases with explanations; the Bitwise Calculator shows shifts and logic operations on a bit grid in plain English; and the Truth Table Generator evaluates expressions with AND, OR, NOT, XOR, NAND, and NOR.
