Length of the longest subsequence such that XOR of adjacent elements is equal to K | ''Function to find maximum length of subsequence having XOR of adjacent elements equal to K.
'' Store maximum length of subsequence.
'' Stores the dp-states.
'' Base case.
'' Iterate over the range [1, N-1].
'' Iterate over the range [0, i - 1].
'' If arr[i]^arr[j] == K.
'' Update the dp[i].
'' Update the maximum subsequence length.
'' If length of longest subsequence  is less than 2 then return 0.
''Driver Code.
'' Input.
'' Prthe length of longest subsequence"
Solution in Python:
 ... Give me a code to length of the longest subsequence such that XOR of adjacent elements is equal to K and the other steps required?
