Of course it did. Cuz you overthunk it. Dramatically.
Your D version allocates memory, for no good reason. I mean, to
store results, but you already have storage for them, so kinda
pointless. Your C version, OTOH, stores results on stack (so
again, why did you allocate for them in D?..), but allocates some
"string builder" for... what, exactly?
The program is filter, or sort + partition. Requires 0
allocations in C or D.
