bottom up parser

Bottom-up parser
A bottom-up parse starts with the string of terminals itself and builds from the
leaves upward, working backwards to the start symbol by applying the productions in reverse. Along the way, a bottom-up parser searches for substrings of the working string that match the right side of some production. When it finds such a substring, it reduces it, i.e., substitutes the left side nonterminal for the matching right side. The goal is to reduce all the way up to the start symbol and report a successful parse.
In general, bottom-up parsing algorithms are more powerful than top-down methods, but not surprisingly, the constructions required are also more complex.
In the bottom-up parsing method, we discuss "shift-reduce" parsing .

Shift-Reduce Parsing:
This parsing method is bottom up parsing .We can think of this process as one of reducing a string w to the start symbol of a grammar . At each step a string matching the right side of a production by the symbol on the left .
