Uses backtracking (DFS-style traversal) to explore all character arrangements from the input string. Tracks each recursion depth (tree level) and stores the generated paths. After recursion, it ...

Tree recursion is a technique used to traverse a tree-like data structure by recursively visiting each node and its children. It’s widely used in computer science, particularly in algorithms that ...
