Which of the following is the most powerful parsing method?
Canonical LR is most powerful method
LR > LALR > SLR
so ans is B
power of PArser is derived on the basis of NO. of language parsed....
CLR could parsed all the language which could parsed by other.....
@srestha LR(1) parsers can parse every language in DCFL set because DCFL are not inherently unambiguos i.e they are gaurenteed to exist atleast one unambiguous grammar that derives them . there is one to one correspondence between the number of DCFL languages and the LR(1)( cannonical LR) parsers but the pther parsers SLR LALR LR(0) donot gaurentee to parse even the unambiguous versions of the grammers corresponding to the DCFL hence the power increases as SHOWN ABOVE
