The DP solution to this problem is very similar DP solution for counting the
number of Dyck words with some additional conditions.
while calculating DP[i][j] you need to check if i+j equals one from the
list of k values. if yes copy the value from the prev row(i.e DP[i-1][j])
instead of assigning it to DP[i-1][j] + DP[i][j-1] since we can add only an
a '(' in position i+j and no ')' can be placed there
