Constructing a Binary Tree from a String and Performing Traversal Sequences
Given the input string abcdefghij, construct a binary tree by inserting characters level by level — that is, fill nodes row-wise from left to right. The resulting tree must yield the following traversal outputs:
In-order: hdibjeafcg
Post-order: hidjebfgca
Level-order: abcdefghij
The construction follows breadth-first insertion: the first char ...
