这是我在洛谷刷的第74道题。#includestdio.hintmain(){inta,b,i;intl;intarr[6];longlongk1;scanf(%d %d,a,b);if(a%70||a0){printf(Sunday);return0;}elseif(b0){printf(Monday);return0;}else{for(i0;i6;i){k*a;arr[i]k%7;}lb%6;if(l0)l5;elsel-1;if(arr[l]1)printf(Monday);elseif(arr[l]2)printf(Tuesday);elseif(arr[l]3)printf(Wednesday);elseif(arr[l]4)printf(Thursday);elseif(arr[l]5)printf(Friday);elseprintf(Saturday);}return0;}反思枚举。
