Ambiguity of Context Free Grammar using the CYK algorithm

The syntax analysis phase of a Compiler is to check syntactic structure of Programming Language construct using Context Free Grammar. Either by using Top-Down or Bottom-Up parsing technique to parse string of a given language. The string of a Language is successfully parsed by parser of Context Free Grammar then that string is syntactically correct. In this paper CYK algorithm is membership algorithm which gives string is member of language generated by Context Free Grammar or not. We have found out the Context Free Grammar is ambiguous or not using CYK algorithm.
