The same solution was submitted in both C++17 (GCC 7-32) & C++20 (GCC 13-64).

AC submission passed with 0 KB on C++17 (GCC 7-32): 257826303

While it resulted in an MLE on C++20 (GCC 13-64): 257826268

The code uses linear memory and it failed on the 8th test which is only of size 10 :/

Can anyone provide a code for Eppstein's k shortest paths algorithm?
