Leetcode Problem 951. Flip Equivalent Binary Trees

951. Flip Equivalent Binary Trees

Leetcode Solutions

Recursive Check for Flip Equivalence

  1. Define a recursive function isFlipEquiv that takes two nodes, node1 and node2, as arguments.
  2. If both node1 and node2 are null, return true.
  3. If one of node1 or node2 is null, or if their values are not equal, return false.
  4. Check the children recursively in two ways: node1.left with node2.left and node1.right with node2.right, or node1.left with node2.right and node1.right with node2.left.
  5. Return true if either of the recursive checks returns true.
