题目意思：
给出n头牛的活动区间，比如区间[SI，sj]和[EI,EJ]，如果前面一个区间完全包含另外一个区间那么说明前一头牛比后一头牛强壮。
思路：根据区间的右区间数来建树，然后用sum[]来维护牛在这些右区间的头数。首先要根据牛的区间顺序进行排序，当然从左像右排序，那么后面进行查询比自己强的牛的时候那么就只用找右区间比自己大的就可以了。那么如何更新呢...

题意给了你N头牛，每头牛的强壮值是一个区间[s,e],如果第 i 头牛比第 j 头牛强壮那么必须满足 Si Ej - Sj；
为了满足这三个条件我们进行排序，先以e降序排为先决条件，若e相等则让s升序排列，如此即可满足三个条件，这道题目任意两头牛的强壮值区间有可能完全一样，这样就不需要重新用树状数组求一次和了，直接赋值即可，这样可以省很多时间，因为已经排序处理了，所以即便区间相等的 肯定就是...
