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 ...
