To understand and analyze deeply, you can debug it. LeetCode. Next: Write a Java program to find the number of bits required to flip to convert two given integers. This is because we construct each node of the binary search tree exactly once, and the number of nodes in a balanced binary search tree is proportional to the number of elements in the array. Aheight-balancedbinary tree is a binary tree in which the depth of the two subtrees of every node never differs by more than one. In place of start creating a tree from the root, we will start creating a tree from the leaf. Repeat until no element is left. public Node createTree(final int[] num, final int start, final int end) { Added if-condition inside helper method to avoid Memory Limit Exceeded.
