Suppose that we have an operation called perm which takes a word and produces all the permutations of that word. Given a language L we define perm(L) to be the language obtained by taking all the permutations of all the words of L. Show that if L is regular then perm(L) may not even be...
Consider the grammar: S aS|aSbS|epsilon Show that this grammar is ambiguous by giving two different parse trees for the string aab. Also give an unambiguous grammar for the language defined by this grammar.

Suppose that we allow a flow network to have negative (as well as positive) edge capacities. In such a network, a feasible flow need not exist. a Consider an edge (u, v) in a flow network G = (V, E) with c(u, v) < 0. Briefly explain what such a negative capacity means in terms of...
Ask a new Computer Science Question
Tips for asking Questions
- Provide any and all relevant background materials. Attach files if necessary to ensure your tutor has all necessary information to answer your question as completely as possible
- Set a compelling price: While our Tutors are eager to answer your questions, giving them a compelling price incentive speeds up the process by avoiding any unnecessary price negotiations
- 1. Identify and describe Trust/Security Domain boundaries that may be applicable to personal computer (workstation) security in a business context.
2. This is a C++ codelab question.
- The "origin" of the cartesian plane in math is the point where x and y are both zero. Given a variable, origin of type Point-- a structured type with two fields, x and y, both of type double, write one or two statements that make this variable's field's values consistent with the mathematical notion of "origin".
- Assume two variables p1 and p2 of type POINT, with two fields, x and y, both of type double, have been declared. Write a statement that reads values for p1 and p2 in that order. Assume that values for x always precede y.
- In mathematics, "quadrant I" of the cartesian plane is the part of the plane where x and y are both positive. Given a variable, p that is of type POINT-- a structured type with two fields, x and y, both of type double-- write and expression that is true if and only the point represented by p is in "quadrant I".
