Array
The array declaration--var arr [10]int,array is defined by [n]
Declare and initialize--arr : = [3]int{1,2,3} or do not write size var arr : = [...] int{1,2,3} or var arr = [3]int{1,2,3}, if no write size can be represented by three points, go will automatically recognize that the Var arr[3]int default is initialized to 0.

There is a recursive code:
Go (int dep, int N, int m)BeginOutput the value of dep.If Dep End
The key is to look at Row 4. If conditions are metDep Then we can go to the next layer for recursion. array X takes only {0, 1}, array c Takes {0, 1, 2}, and array A and array B takes 0 ~ M and

There is such a process:
Go (int dep, int n, int m)BeginOutput the value of DEP.If DEP End
Where x[] has a value of 0 or 1...c[] with a value of 0 or 1 or 2 .... Now tell a[],b[],c[]. What is the deepest possible question of this process?
