將整數(shù)轉(zhuǎn)換成字符串:void itoa(int,char); 例如itoa(-123,s[])則s=“-123”; u2合唱團在17分鐘內(nèi)得趕到演唱會場,途中必需跨過一座橋,四個人從橋的同一端出發(fā),你得幫助他們到達另一端,天色很暗,而他們只有一只手電筒。一次同時最多可以有兩人一起過橋,而過橋的時候必須持有手電筒,所以就得有人把手電筒帶來帶去,來回橋兩端。手電筒是不能用丟的方式來傳遞的。四個人的步行速度各不同,若兩人同行則以較慢者的速度為準(zhǔn)。bono需花1分鐘過橋,edge需花2分鐘過橋,adam需花5分鐘過橋,larry需花 10分鐘過橋。他們要如何在17分鐘內(nèi)過橋呢?(有個同濟的學(xué)生寫文章說他當(dāng)時在微軟面試時就是碰到了這道題,最短只能做出在19分鐘內(nèi)過橋,微軟的人對他講這樣的結(jié)果已經(jīng)是不錯的了!)
