But in one-dimensional case, the push-free segment tree (this is how I named it about 3.53.5 years ago when it came up during some training contest) allows us to write the code without pushes giving the possibility to mark sum queries const and improving the const-safety of your code....
The segment tree can be adapted to retrieve not only the minimum element in a range but also various other functions. Here are some examples taken from otherwise difficult contest problems: Maximum[edit] Analogously to the minimum: all min operations replaced by max. Sum or product[edit] Ea...

bzoj#4695 最假女选手 segment tree beats 多种操作 题意: 思路: \(2,3\)操作其实就是区间的最值操作,类似于一个最值操作的维护过程,我们考虑维护最大值,次大值,最大值出现次数,最小值,次小值,最小值出现次数,加的懒标记,区间和 其实思路比较常规,就是代码量稍大点,容易写错,由于区间加减操作并不会...
