I was trying to do that prime factorization CMC in Gaia and wondered why my computer froze when I ran it. I used the wrong operator, and evidently filtering the range [1 .. 12!] for only odd numbers uses a lot of memory
@Ethcad Hm, that would actually be an interesting challenge - you provide a working implementation, and we provide the golfiest version of it. Look into tips as opposed to a regular challenge.

CMC: Given a string s, find the number of substrings of s with length 3 or greater that are palindromic. The substrings may be overlapping. Example: "abcbab" -> 3 (abcba, bcb, and bab)
So say your running an eCommerce site, and are writing a function to take an array of an order and pack it into boxes.
For example say you have a collection of all the products of the order:
[{ product: "c5b3eb47", weight: 1},
{ product: "c5b3eb47", weight: 1},
{ product: "c5b3eb47",...
RE perfect squares, did anybody know this about perfect squares? I remember thinking I was a genius when I discovered this when I was 11, only to realize it was a known fact in math
