Explain Top down parsing.

Top down parsing: Specified an input string, top down parsing tries to derive a string identical to this by successive application of grammar rules to the grammar's distinguished symbol. While such a string is acquired, a tree showing its derivation would be the syntax tree for an input string. Therefore if ? is input-string, a top-down parse finds a derivation sequence.
