英语好难读……题是水题,瞬间就过了,很裸的TopoSort()。 大意是给一张图做拓扑排序,可是有很多话我还是没太明白,英语太菜了,555…… give the floor to sb.原来是让某人发言的意思…… 还有Martians bud when they want and where they want我一直没懂,bud应该怎么解释?火星人像植物一样发芽? 以及,题目是说,一个火星人可以有一到十个parent,一到100个children么?貌似是这个意思,不过总觉得怪怪的…… 还是我想象力不够呢? 求各位大大指教…… Followed by: Post your reply here: |
