# Probability Of Knight In The Chessboard

medium

1. You are given a N*N chessboard and the starting position of the knight in the chessboard. 2. The rows and columns are 0 indexed, so the top-left square is (0, 0), and the bottom-right square is (N-1, N-1). 3. You have to find the probability of knight to remain in the chessboard after exactly k number of moves. Note -> The knight continues moving until it has made exactly K moves or has moved off the chessboard.

## Constraints

1 <= N <= 25 0 <= K <= 100 0 <= r,c <= N-1

## Format

### Input

A number N A number K Two numbers r and c(starting row and column position of knight in the chessboard).

### Output

Check the sample output and question video.

## Example

Sample Input

```.css-23h8hz{color:inherit;font-size:0.875rem;line-height:1.125rem;letter-spacing:0.016rem;font-weight:var(--chakra-fontWeights-normal);white-space:pre-wrap;}3 2 0 0```

### Sample Output

```.css-3oaykw{color:var(--chakra-colors-active-primary);font-size:0.875rem;line-height:1.125rem;letter-spacing:0.016rem;font-weight:var(--chakra-fontWeights-normal);white-space:pre-wrap;font-family:Monospace;}0.0625 ```
