number spiral (1) 썸네일형 리스트형 [C/C++] Project Euler #28 - Number Spiral Diagonals This program can actually work by defining the desired array, arranging the numbers, and then calculating the sum of the diagonals.Even if you do it this way, it doesn’t take a significant amount of time.However, when I first started writing these Project Euler posts, I focused on figuring out how to calculate more efficiently, so I tackled this problem by reducing its complexity.If you know how.. 이전 1 다음
