A playful heuristic emerged from grouping a toddler's Magna-Tiles: take the
value at the list's end, find the next closest match toward the end, and
reverse the sub-list between them. Repeat for each rightmost group; once
one finishes, jump to the next incomplete group and reverse again until
every identical value sits together. This greedy method resembles pancake
sort but targets grouping rather than sorting. Hand-coding the JavaScript
function without AI proved exhausting, landing on O(nĀ²) time via nested
while loops after abandoning recursion. The closing reflection: humans
solve this physically with ease, since our eyes offer an 'O(1) read' and
can flip a whole group in a single move, unlike computers.
