This function take the signal which you want to find FFT, for m bit you can also call the function without entering a signal or number of points, because there is default values for y and m which are y = sin(2*pi*50*t)+sin(2*pi*120*t) m=3 you can see the steps of order reversing used as built-in function but non others. you will also see the taking butterfly tree steps. for more information read the help file of function. in future this can be improve as selective radix or any other feature you suggest please notice me for any sugestion.

Binary tree by the LISP S- Expression to that of its rules as follows: Empty tree = () Tree = (Integer left subtree right subtree) Leaf node = (integer () ()) ★ programming tasks The problem is given by an S-expression LISP decision tree to ask whether there is a leaf node from the root to the path P, so that all nodes on the path and equal to a given integer I. ★ data entry Given by the input data file input.txt. Each input data includes multiple sets of data, each data contains an integer I and An S expression T (on behalf of binary tree), integral I can be with a number of spaces. S expression across multiple lines, may contain redundant Spaces. ★ output The results will be output to the file output.txt. If there is a path p, so that the path on all nodes and equal to I, Then output "yes", otherwise output "no". Sample input file output file
