1 2 3 4 5 6 7 8 9 10 11 12 13 | if ( v15 > 0 && v16 > 0 && v15 <= v16 && v16 + v15 == 117738 ) { v13 = "Accepted!\n"; if ( v15 * v16 == 3457897337i64 ) goto LABEL_28; } break; } } } }LABEL_27: v13 = "Wrong answer!\n"; |
由这段代码可知
v15 + v16 = 117738
v15 * v16 = 3457897337
应用韦达定理的逆定理可得
xx+117738x+3457897337=0
得到-61637,-56101
去掉负号,根据v15 <= v16
得到:56101-61637
