Codeforces Round #484 (Div. 2) B. Bus of Characters
Example 1 input 2 3 1 0011 output 2 1 1 2 Example 2 input 6 10 8 9 11 13 5 010010011101 output 6 6 2 3 3 1 4 4 1 2 5 5
题目大意:
公交车有n行,每行有2个座位,每一行的座位大小都为w[i],现在有两种人,第一种会先坐空行的位子,再在空 行里面选择最大w[i]的位子坐;第二种人则是选择有人坐的一行,在那些行里选择位子w[i]最小的
分析:
先将位子按w排序,第一种人选定好后,将他的座位放入队列里,然后第二种人从队列里选择w最小的就行了
