I have to find cyclometric complexity for this code and then suggest some white box test cases...
Imagine I have a stack-based toy language that comes with the operations Push, Pop, Jump and If.
I have a program and its input is the toy language. For instance I get the sequence
Push 1
Push 1
Pop
Pop
In that case the maximum stack would be 2. A more complicated example would use branches.
Push 1
Push true
If .success
Pop
Jump ....
Can Any One explain this Language how we converted to CFG
Give a CFG for the CFL: {ai bj ck | i ≠ j or j ≠ k } //ai mean a^i
I have the answer but I need an explaination (Step By Step)
The answer :
S --> S1|S2
S1 --> A Eab|Eab B|S1 c
A --> a|aA B--> b|bB
Eab --> Q|a Eab b
S2 --> Eac C|A Eac
C --> c|cC
Eac --> ...
Long time admirer first time inquirer :)
I'm working on a program which derives a deterministic finite-state automata from a context-free grammar, and the paper I have been assigned which explains how to do this keeps referring to "arbitrary probabilistic context-free grammars" but never defines the meaning of "arbitrary" in relation to...
Trying to figure out removing left recursion in context free grammars. I'm used to certain forms, but this one has me a bit boggled.
S --> S {S} S | (A) | a
A --> {S} A | epsilon
I also have to design a decent parser, which I can do. However, figuring out this left recursion (especially on the first one) has me confused.

Write a Context-free grammar(CFG) that pass all assignment statements of the form
id:=expression
where expression is an arithmetic expression involving integers,real numbers,identifiers,operators like +,_,*,/,%,^ and parenthesis().use to construct Recursive descent parser(RDP) for the same.
