Explain and implement in C++ the FFT algorithm "Cooley-Tukey". Also, implement the naive DFT and compare the naive DFT with the FFT using: a sample of the signal x(t) = t and then x(t)=t^5. Use your own C++ classes and create a GUI with QtCreator.
Requirements
1.- Application compiling and running, application robustness (try many cases!),2.- Quality of programming: coding style, comments, use of memory, functions variables used, ...3.- GUI efficiency and visual aspect,4.- Project management: choice of classes (UML), links between algorithm classes and GUI classes, ...5- Proof of correctness,6.- Comparison of the theoretical time efficiency vs observed one.
Katt wishes you to create an algorithm that, given a string X, determines efficiently how many ways X can be broken up into sequence of words.
Give an algorithm to find the schedule that obtains the maximum amount of profit, assuming that all processing times are integers between 1 and n.
Structure of such two-stack data type would consist of two arrays and two top pointers. Describe why this may not be a spacewise efficient implementation.
Data structures for a single algorithm
Create the O(|V | + | E |) time algorithm which, given times ti and the dependencies, determines minimum time required to complete all the tasks.
