    题目:Transformation

    这是我参考的博客:https://blog.csdn.net/a664607530/article/details/74563018
    总结:这题是看了将近一个上午才看明白,这里面线段树的节点保存的是这个节点所在区间内相同的元素的值,比如1~mid,这个节点的值为3,说明的是1 ~mid,所有元素的值都是为3

    if(lazy[rt]){
        lazy[ls] = lazy[rs] = true;
        lazy[rt] = false;
        tree[ls] = tree[rs] = tree[rt];
    }
    

    这段代码的意思是住下继续扩展,因为当前区间不满足操作

    void pushup(int rt){
        if(lazy[rs] == false || lazy[ls] == false){
            lazy[rt] = false;
        }else if(tree[ls] != tree[rs]){
            lazy[rt] = false;
        }else {
            lazy[rt] = true;
            tree[rt] = tree[ls];
        }
    }
    

    这段代码就有点类似于合并了,根据下面两个子区间的情况,判断父亲区间是否要发生变化。

    #include <stdio.h>
    #include <string.h>
    #include <algorithm>
    #define mid (start+end)/2
    #define ls (2*rt)
    #define rs ((2*rt)+1)
    const int mod = 10007;
    const int N = 1e5+5;
    using namespace std;
    
    int tree[N<<2];
    bool lazy[N<<2];
    int n,m;
    
    void pushup(int rt){
        if(lazy[rs] == false || lazy[ls] == false){
            lazy[rt] = false;
        }else if(tree[ls] != tree[rs]){
            lazy[rt] = false;
        }else {
            lazy[rt] = true;
            tree[rt] = tree[ls];
        }
    }
    void update(int rt,int start,int end,int l,int r,int v,int op){
        if(lazy[rt] && start >= l && end <= r){
            if(op == 1){
                tree[rt] = (tree[rt]+v)%mod;
            }else if(op == 2){
                tree[rt] = (tree[rt]*v)%mod;
            }else {
                tree[rt] = v%mod;
            }
            return;
        }
        if(lazy[rt]){
            lazy[ls] = lazy[rt] = true;
            tree[ls] = tree[rs] = tree[rt];
            lazy[rt] = false;
        }
        if(l <= mid) update(ls,start,mid,l,r,v,op);
        if(r > mid) update(rs,mid+1,end,l,r,v,op);
        pushup(rt);
    }
    int query(int rt,int start,int end,int l,int r,int p){
        if(lazy[rt] && start >= l && end <= r){
            int ans = 1;
            for(int i = 1;i <= p;i++){
                ans = (ans*tree[rt])%mod;
            }
            ans = (ans*(end-start+1))%mod;
            return ans;
        }
        if(lazy[rt]){
            lazy[ls] = lazy[rs] = true;
            lazy[rt] = false;
            tree[ls] = tree[rs] = tree[rt];
        }
        int ans = 0;
        if(l <= mid) ans += query(ls,start,mid,l,r,p);
        if(r > mid) ans += query(rs,mid+1,end,l,r,p);
        return ans%mod;
    }
    void traver(){
        for(int i = 1;i <= 9;i++){
            printf("%3d",i);
        }
        printf("\n");
        for(int i = 1;i <= 9;i++){
            printf("%3d",lazy[i]);
        }
        printf("\n");
        for(int i = 1;i <= 9;i++){
            printf("%3d",tree[i]);
        }
        printf("\n\n");
    }
    int main(){
