You are given a grid with2rows and3columns of squares. The color of the square at thei-th row andj-th column is represented by the characterCij. Write a program that printsYESif this grid remains the same when rotated180degrees, and printsNOotherwise. Constraints Ci,j(1≤i≤2,1≤j...
直接模拟取模。 B - Checkpoints 暴力枚举。 C - Digits in Multiplication 一开始想复杂以为是质因数分解,因为只要求找出所有的 p a i r ( A , B ) , A B = N pair(A,B),AB=N pair(A,B),AB=N 显然可以暴力枚举 A A A。 D - Maximum Average Sets 贪心,显然取 a a a个最大的是最优的...
