A lot of the time I usually feel familiar with a thing put on a coat we don't knowIn fact, we are not familiar with it.The prototype of this problem is to give you a series of 01 sequence can randomly modify the value of a fixed position We're going to convert this to the coordinates. If 2 values are the same or 1 otherwise 0 then each time we modify the character of a string, the sequence value corresponding to that position may change, not necessarily the exact modification.What you're asking

Counting haybales (segment tree)

Nnonnegative integers, each at the most 100,000, indicating how many haybales is initially in each field.Each of the next Q lines contains a single uppercase letter, either M, P or S, followed by either both positive integer S A and B (1≤a≤b≤n), or three positive integers A, B, and C (1≤a≤b≤n; 1≤c≤100,000). There'll be three positive integers if and only if the uppercase letter is P.If the letter was M, print the minimum number of haybales in the interval of ... B.If the letter was P, put C new

Test Instructions: To a string of length n, q operations, each operation put [l,r] sort, k=0 non-increment, k=1 non-decrement.The following: The complexity of using count sorting is o ( n q ) , unable to pass, but with some revelation.You can see that the count is the interval sum, the sorting is the interval update, can be maintained with the segment tree.The practice is to establish 26 line segment trees, and the I tree maintains the position information of the letter I.Whe
