Leetcode Problem 797. All Paths From Source to Target

797. All Paths From Source to Target

Leetcode Solutions

Define a helper function backtrack that takes the current node and the path traversed so far as arguments.
If the current node is the target node, add the current path to the list of all paths.
Otherwise, iterate over all the neighbors of the current node.
For each neighbor, append it to the current path and recursively call backtrack with the neighbor as the new current node.
After exploring all paths through the neighbor, backtrack by removing the neighbor from the current path.
Call backtrack with the start node (0) and an initial path containing only the start node.
