解一题,补过.

把钟用60数字表达,时用X,分用Y,(X,Y)表[X/5]时Y分.(X,Y)与(Y,X)合理就是

(X-[X/5]*5)*12<= Y <(X-[X/5]*5+1)*12 和 (Y-[Y/5]*5)*12<= X <(Y-[Y/5]*5+1)*12

有144个解.如(28,27),...(28,32)...即5时27分,...5时32分...是"AMBIGUOUS".

余龄过孔子寿,难免有错,望指正.

• 恰恰相反,离散的才有这144组解.(12*60/5=144) -jinjing- ♀ (504 bytes) () 11/27/2012 postreply 18:07:32
