You were right. I debugged is_king_tableau and found a minor fault in it. I
fixed it like this:
def is_king_tableau(t):
"""A function which tests if a semistandard tableau is a King
tableau."""
if SemistandardTableau(t):
if t[0][0] < 1:
return False
"""checks tableaux of shape (2,1)"""
elif (t[1][0]%2)==0:
return False
for i, row in enumerate(t):
if row[0] <= 2*i:
return False
return True
I ran a couple of test cases and got my desired output. Is there a better
way to check the above condition or what I did is fine?
Thanks,
Soheli
