這題就是，小學(xué)的時(shí)鐘角度計(jì)算，對(duì)
| #include <stdio.h> #include <math.h> int main(){ int H, M; float H_A, M_A, A; // A for angle. while(scanf("%d:%d", &H, &M) != EOF && (H || M)){ // if H:M = 0:00 then bye bye //scan the time and translate them into angle. //need to use float to divide or it will be int I guess. H_A = H * 30.0 + (M / 60.0) * 30.0; M_A = M * 6.0; A = fabs(H_A - M_A); printf("%.3f\n",(A > 180.0) ? 360.0 - A : A); } return 0; } |

阿這題就是，切披薩，(n + (n - 1) + ... + 1) + 1
| #include <stdio.h> int main(){ int N, result; while(scanf("%d", &N) && (N >= 0 && N <= 210000000)){ while(N != 0){ result += N; N--; } printf("%d\n", result + 1); result = 0; } return 0; } |
這甚麼新年禮包嗎?
讓我再放鬆一天(?
是說(shuō)下一題就是101
剛開始練習(xí)遇到的惡夢(mèng)
或許可以開啟復(fù)仇計(jì)畫?
從4/5變成2/5之類的
