Problem Description N个气球排成一排,从左到右依次编号为1,2,3-.N.每次给定2个整数a b(a <= b),lele便为骑上他的"小飞鸽"牌电动车从气球a开始到气球b依次给每个气球涂一次颜色.但是N次以后lele已经忘记了第I个气球已经涂过几次颜色了,你能帮他算出每个气球被涂过几次颜色吗? Input 每个测试实例第一行为一个整数N,(N <= 100000).接下来的N行,每行包括2个整数a b(1 <= a <= b <= N…

水题,练习一下树状数组实现区间更新. 对于每个区间,区间左端点+1,右端点的后一位-1,查询每个位置的覆盖次数 #include <cstdio> #include <cstring> ; int N, C[MAXN]; int lowbit( int x ) { return (-x)&x; } void update(int x, int add) { for(int i = x; i <= N; i += lowbit(i)) C[i] += add; retu…

http://codeforces.com/problemset/problem/12/D 这里的BIT查询,指的是查询[1, R]或者[R, maxn]之间的最值,这样就够用了. 设三个权值分别是b[1], b[2], b[2]; 首先,先把b[1]值离散化,离散成一个个id,那么只能是在id比较大的地方找了.然后把b[2]排序,倒序查询,也就是先查询最大的,当然它是没可能自杀的,因为它已经最大了,然后查询完后,把它压进bit后,以后在bit查询,就不需要管b[2]了,因为在bit里面的b[2…
