Subject description:
Confucius said: "three-line, must be my teacher choosing the good from it, their bad corrections.." The title given value relationships A, B, C three people capacity: the ability to determine the value of A 2 is a positive integer; ability value of the two digital positions exchange ability value of a is b; X and b is two times the poor ability value of the prop; ability value Y b is the propionate times. Please point out who is stronger than you should, "from the" weak who should "corrections" than you. Input format: Enter the number of three in a row are given, followed by: M (your own ability value), X and Y. No more than three numbers are positive integers 1000. Output Format: First, the ability value output in line A, and then sequentially outputs A, B, C and three of your relationship: if it is better than you, Cong output; the Ping equal output; the output is weaker than you Gai. Meanwhile separated by a space, the line from beginning to end may not have the extra space. Note: If the solution is not unique, the maximal solution places A subject judged; if the solution does not exist, the output No Solution. Input Example 1: 4837 Output Sample 1: 48 the Ping Cong Gai Input Sample 2: 48 116 Output Sample 2: No Solution
Finishing ideas:
A reverse traversal (99-10), the first to find a solution in line with requirements of the subject propylene is not necessarily an integer type is set to double
I AC Code:
// three rows 1088 # the include <stdio.h> # the include <math.h> // output their numerical relationship with ABC void Print (int, Double); int main (void) { int M, A, B; respectively, and their // AB double C; // propan not be an integer int X-, the Y; int in flag = 0; // flag absence Solutions scanf ( "% d% d% d", & M, & X, the Y &); for (a = 99; a> = 10; A--) { // a calculated value B B B = (a% 10) + a * 10/10; C = ABS (AB) * 1.0 / X- ; IF (the Y B == C *) { In Flag =. 1; BREAK; } } // if a solution, in accordance with the rules of the output IF (In Flag ==. 1) { the printf ( "% D", A); Print (M , A); Print (M , B); print(M,C); } // 否则输出无解 else { printf("No Solution\n"); } return 0; } void print(int M, double N) { if (M == N) printf(" Ping"); else if (M < N) printf(" Cong"); else printf(" Gai"); }
