Using queues to implement a stack 10 points; individual-only in lecture, we considered two implementations of the stack adt: one using an array and one using a linked list. devise a third implementation of the stack adt that uses two queues, q1 and q2. use pseudocode to describe how you would use q1 and q2 to implement the stack operations push, pop, and peek, and give the running time of each operation using big-o notation. explain briefly how you came up with the big-o expressions that you use. your algorithms for these methods may use q1, q2, and a constant number of additional variables (either fields of the stack object or local variables of the method). they may not use an array, linked list, orbther data structure. you may assume that the queues support the operations in our queue interface, and that they can store an arbitrary number of objects of any type.

Assume that you have an sorted array of records. assume that the length of the array (n) is known. give two different methods to search for a specific value in this array. you can use english or pseudo-code for your algorithm. what is the time complexity for each algorithm and why?

Write a method that takes in an array of point2d objects, and then analyzes the dataset to find points that are close together. be sure to review the point2d api. in your method, if the distance between any pair of points is less than 10, display the distance and the (x,y)s of each point. for example, "the distance between (3,5) and (8,9) is 6.40312." the complete api for the point2d adt may be viewed at ~pf/sedgewick-wayne/algs4/documentation/point2d.html (links to an external site.)links to an external site.. try to write your program directly from the api - do not review the adt's source code.

6. write a user-defined matlab function for the following math function: r() = 4cos(4sin ) the input to the function is (in radians) and the output is r. write the function such that can be a vector. a) use the function to calculate r(/6) and r(5/6). b) use the function to plot (polar plot) r() for 0 ≤ ≤ 2. hint: use “ polar” and/or for “polar plot in matlab." include the title “'r(\theta)=4cos(4sin(\theta))”
