Show that the following grammar is ambiguous. Hint: Show two different leftmost or rightmost derivations for the same string. Equivalently, you can show two different parse trees for the same string. <expr> ::= <expr> + <expr> | <expr> - <expr> | <expr> * <expr> | <expr> / <expr> | int int ::= 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 Using this grammar show that ambiguity is not acceptable...

Define a context-free grammar (CFG) that generates exactly the following language. B = {1'0'ik | i+j = k or i+k=j with i, j, k > 0} Both ambiguous and unambiguous grammars are acceptable (it does not matter in this question). For grading purposes, please use as the starting variable. Alphabet E = {0,1}

In Java, building a recursive descent recognizer that prints concrete syntax trees without building them. A sample input file appears below. It consists of six regular expressions, one on each line. Call this inputFile2.txt. two t|w|o [two] [ˆtwo] t(oo?|wo) (\<(/?[^\>]+)\>) For each statement in the file, you are to print a concrete syntax tree as the parse proceeds. The required output is shown below. The amount of horizontal indentation depicts the nesting level of the node within the tree. The...
