The tree array in this question is a little characteristic, that is, the so-called discretization is required. It seems mysterious to start to hear this name, but it is actually very simple. It is to convert the value of an array arr into a group of

Solution: directly add the template. Extended Euclidean template:   typedef long long LL;LL ex_gcd(LL a,LL b,LL &x,LL &y){ if(b==0) { x=1; y=0; return a; } LL d=ex_gcd(b,a%b,x,y); LL t=x; x=y; y=t-a/b*y;

In Objective-C, you can use # import and @ class to reference other types. But do you know the differences between the two?@ Class is called forward-class. You often see the reference through @ class in the header file definition, because when you

The last element in the structure can be an array of unknown sizes. This array is a flexible array. However, there must be at least one other member before the flexible array in the structure. The flexible array member allows the structure to
