Sorting Design and Analysis For this assignment, you need to study the performance of 2 designed algorithms using different logic. You need to write a program in C language that takes N (size of input) then write the following functions/methods: int[] GenerateValues (N) where N is random int values between 0 and N-1. DistinctValues Algorithms: int findDistintValuesWithoutSort( A, N) to count the number of distinct values in A without sorting algorithm. int findDistintValuesWithSort( A, N) to count the number of distinct values using any sorting algorithm (i.e., quicksort or merge sort or heapsort). Print the execution time for each method to find the distinct values where N = 103, 104, and 105. Note the execution time in a table and discuss your results in the document file. Discuss the execution time compared to your big -O analysis of the 2 DistinctValues algorithms.

[Unbalanced Rod] Given a set of n weights {w₁,..., wn} and a rod of length n - 1 inches, we can attach the weights to the rod at hooks placed at one inch distances apart as shown in the figure below. -1". /10 2 3 12 2 4 We can attach a weight to any hook but no two weights can be attached to the same hook and we have to attach all the weights. For any given assignment of weights to hooks, we can compute the location of the center of mass of the rod and the weights according to the following equation (neglecting the weights of the rod and the hooks). where 0 ≤ Pi≤n-1 is the position of weight along the rod. For example, in the figure shown above, the center of mass is computed as C= C = i Wi Pi Σi Wi 10 0+2 1+3·2+4·3+12.4 +2.5 10+2+3+4+12+2 78 33 The problem is to find an assignment of weights to hooks that makes the center of mass as far as possible to the left, i.e., minimize the value of c. Answer the following questions. 1. Describe a greedy algorithm that finds the assignments that…

0. Good binary strings are strings made of Os and 1s where there are no two consecutive Os. For example, 1011011101, 011010 etc. How many good binary strings of length k are there? [Hint: First you may try to find the highest possible number of Os in such strings in terms of k . It can be done separately for odd and even k. Use the Floor function to generalize. Giving the final answer in summation (E) form will suffice.]
