3. Consider the following grammar: expr term term tail term-tail-) add-op term term-ail 1 ε term → factor factor-tail factor. tain ε factor (expr) id literal add-op → +1 Draw a syntax tree for parsing each of cdf + (a25 + 84), (a25 + 84)*cdf, 84*cdf+ a25, a25+84 cdf a25*84*cdf. Note that a25 and cdf are identifiers and 84 is a literal You are not asked to do the tedious parsing process with stack snapshots. Instead
