Hihocoder #1143: Domino Coverage problem • Time limit:10000msSingle Point time limit:1000msMemory Limit:256MBDescribeDominoes, an ancient toy. Today we are going to look at the problem of Domino coverage:We have a 2xN strip board and then use the 1x2 dominoes to cover the entire board. How many different coverage methods are there for this chessboard?For example, for a board with a length of 1 to 3, we have the following types of coverage:Hint: Domino OverlayTip: How to quickly calculate results

Yesterday, I encountered a question like 1, 1, 2, 3, 5, 8, 13, 21.... What is the value of 30th?CodeThe implementation is as follows: 1 // 30th, 13, 21 ...... what is? 2 // Use recursion to calculate the Fibonacci sequence value of a specified number of digits 3 // Fn = f (n-1) + f (n-2) 4 Public Static Int Getfibonaccinumber ( Int Index) 5 { 6 If (Index 0

We can use the small rectangle of 2*1 to cover the larger rectangle horizontally or vertically. Can you tell me how many methods 1 use the array structure traversal method if the small rectangle with n 2*1 covers a 2*n large rectangle without overlapping (target==1| | target==0) return1; int[]arr=newint[target+1]; arr[0]=1; arr[1]=1; for (inti=2;i A variant of the Fibonacci sequence on a practical issue

Here's how it's recursive:Private Static int Fib_re (int N) { Re_count++ ; if (n1) { return1; } Else { return fib_re (n1) + fib_re (n-2);} }Here is the dynamic plan:Private Static int Fib_fast (int n,dictionaryintint> dic) { Fa_count++ ; if (!
