Write all solutions for a^3+b^3 = c^3 + d^3, where a, b, c, d lie between [0, 10^5]

Won't run on Sololearn though (Sololearn is too slow) https://code.sololearn.com/cTegHfwQnnNA/?ref=app

All solutions? Wouldn't that be true every time a equals c and b equals d (or the other way round)? There are billions of solutions even if a, b, c and d are integers. /Edit: I just checked for the range [0, 10^2] and found 20,260 solutions... I'm not going to write them all down 🤓

So, only solutions like 96³ + 12³ = 90³ + 54³ or 54³ + 20³ = 48³ + 38³? There are still hundreds of solutions even in the range [0, 10^2].

Yes, I'm sure. I wrote a funny little C program

What do you need it for? We're not supposed to do other people's homework here...
