Probability of Knight
Medium Accuracy: 44.92% Submissions: 1065 Points: 4

Given an NxN chessboard and a Knight at position (x, y). The Knight has to take exactly K steps, where at each step it chooses any of the 8 directions uniformly at random. Find the probability that the Knight remains in the chessboard after taking K steps, with the condition that it can’t enter the board again once it leaves it.

Example 1:

Input : N = 8, x = 0, y = 0, K = 3
Output: 0.125000


Example 2:

Input: N = 4, x = 1, y = 2, k = 4
Output: 0.024414


You don't need to read or print anything. Your task is to complete the function findProb() which takes N, x, y and K as input parameter and returns the probability.

Expected Time Complexity : O(N 3)
Expected Space Complexity: O(N3)

Constraints:
1 <= N <= 100
0 <= x, y <= N

0 <= K <= N
