Create a Number Tree - Form a Tree from the Given Numbers

Combine a list of numbers and they stitch themselves into a tree: each pair merges upward, generation by generation, until a single root stands. 2+3=5, 5+1=6, then 5+6=11 - the combined total climbs a real branch-and-merge ladder you can see.

Create a Number Tree turns a flat list into a branching diagram. Merge neighbours by sum to build a clean pyramid, or merge the smallest first for a compression-style Huffman tree. Up to 1000 lists per run, each drawn as a labelled text-art tree.

• Binary tree art: Numbers merge into a branching tree.
• Two modes: Ordered sum pyramid or smallest-first Huffman.
• Root total: Sum mode shows the grand total on top.
• Clear branches: Monospace connectors make mergers obvious.
• Batch mode: Up to 1000 trees per run.
• Copy or download: Export every tree.

1. Enter number lists - one list per line, values separated by spaces.
2. Pick a merge mode - ordered sum or smallest-first.
3. Generate - neighbours / smallest pair up and merge upward.
4. Read the levels - inputs at the bottom, combinations above, root on top.
5. Copy or download - the tree output.

1. 2 3 5 1 9: sum mode pairs (2+3)=5 and (5+1)=6 and (6+9)=15, then (5+6)=11, root (11+15)=26 - the total.

2. 5 1 2 2 1: minimum mode always pairs the smallest two - a tight, balanced Huffman-style tree.

3. 1 1 1 1 1 1: every merge sums to 2, branching into a regular balanced bush.

4. 10 20 30: neighbours merge 10+20=30 then 30+30=60 - a small three-leaf tree.

5. 7 8: the simplest tree - two leaves merge straight to root 15.

• See merging: Flat lists become branchy structures.
• Two strategies: Ordered pyramid or compression-minded.
• Total on top: Sum mode shows the grand root instantly.
• Batch trees: Hundreds of diagrams per run.
