Write an R program that makes a dotplot of two DNA sequences S1= ATGCTA and S2=
ATTCTA by plotting a dot at every position where the two sequences share an identical letter.
Use the function “makeDotPlot1()” to make a dotplot between sequences setting the argument
“dotsize” to 0.1 (this determines the radius of each dot plotted). Do you find the same regions
and if not, can you explain why?

- write a program in C++ Fibonacci NumbersThe Fibonacci numbers are defined by the sequencef1 = 1f2 = 1fn = fn-1 + fn-2Reformulate that as5t1 = 1;t2 = 1;nextTerm = t1 + t2;After that, discard t1, which is no longer needed, and set t1 to t2 and t2 to nextTerm.Repeat fnew an appropriate number of times. Implement a program that given a numberN, prints the first N numbers in the Fibonacci sequence. For example, given the number8, the output isThe Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13, 21Write a program in c language to analyze the letter frequencies in a block of text. Ignore case (upper and lower count the same). It should count the number of times each letter appears in the text, the number of times each pair of letters appears, and the number of times each sequence of 3 letters appears. Your program should sort the counts of single letters, pairs of letters (bigrams), and triples of letters (trigrams), then print the non-zero values in decreasing order. For single letters, print all non-zero values; for bigrams and trigrams, print the first 30 non-zero values.(monoalphabetic substitution ciphers)write a python function called subsequence() that finds the longest common subsequence of two DNA strands. The function should take two DNA strands (strings) as input and should return the longest common subsequence. example: subsequence ("AATTCAT", "CAT") return "CAT" subsequence ("CAAAT", "CAT") return "CA subsequence("CCG", "TTA") returns "" subsequence ("AATGTACCC", "AATCTTACCT") return "TTACC" subsequence ("AATCTTAGCC", AATCAAAGCC") returns "AATC"
- Write a program in C++ which allows the user to input 3 sets (A,B,C) and to display the cartesian product AxBxC of the 3 sets, and then calculate the number of elements in AxBxC. Keep in mind, if the the input looks like A={a,b,c}, B={1,2,3,4}, C={A,B,C,D,E}, the output should look like “AxBxC = {(a,1,A), … ,(c,4,E)} and it has 60 elements”Write a program using Scilab that includes the following lines x = linspace(0,1,N); y = sin(%pi*x/2); xi = linspace(0,1,100); The program should use the interp1 function to perform spline interpolation of the (x,y) data at the 100 xi points. These interpolated values should be compared to the exact values of the function sin(π x /2) and your program should use this to find the smallest number of samples N that gives an interpolation with an error of no more than ±0.00001Implement the quadratic_formula() function. The function takes 3 arguments, a, b, and c, and computes the two results of the quadratic formula: x1=−b+b2−4ac2a x2=−b−b2−4ac2a The quadratic_formula() function returns the tuple (x1, x2). Ex: When a = 1, b = -5, and c = 6, quadratic_formula() returns (3, 2). Code provided in main.py reads a single input line containing values for a, b, and c, separated by spaces. Each input is converted to a float and passed to the quadratic_formula() function. Ex: If the input is: 2 -3 -77 the output is: Solutions to 2x^2 + -3x + -77 = 0 x1 = 7 x2 = -5.50 code: # TODO: Import math module def quadratic_formula(a, b, c):# TODO: Compute the quadratic formula results in variables x1 and x2return (x1, x2) def print_number(number, prefix_str):if float(int(number)) == number:print("{}{:.0f}".format(prefix_str, number))else:print("{}{:.2f}".format(prefix_str, number)) if __name__ == "__main__":input_line = input()split_line = input_line.split(" ")a =…
- Write a program in Python with a function squareRoot(x, epsilon) that uses bisection search to return a number y that is close enough to the square root of x, so that abs(y**2 - x) < epsilon.Write a function that gets an array of points and sorts the array using qsort(). Given two points a=(ax,ay) and b=(bx,by) we compare them as follows: 1) if (ax)2+(ay)2 < (bx)2+(by)2, then a should come before b in the sorted array. 2) if (ax)2+(ay)2 = (bx)2+(by)2, then we compare the points by the x coordinate. Remark: For a point a=(ax,ay) the quantity ((ax)2+(ay)2)½ is the distance of a from the (0,0). That is, we sort the points according to their distance to (0,0), and if for points at the same distance, then we sort them according to the first coordinate. You will need to implement the comparison function, and apply qsort() on the array with this comparison function. For example: - Input: [(3,2), (7,1), (1,1), (3,4), (5,0), (7,1)] - Expected output: [(1,1), (3,2), (3,4), (5,0), (7,1), (7,1) ] Explanation: (1,1) is first because 12+12=2 is the smallest (3,2) is next because 32+22 = 13 is the second smallest Both (3,4) and (5,0) have the same sum of squares, 25, but 3<5 so…Write a function triple_riffle_repeat(mylist,n) which takes as input a list (again with length a multiple of 3) and outputs the result of doing a 3-way riffle shufffle n times Write a function period(m) which takes as input a number m (which we will always take as a multiple of 3) and outputs the smallest positive integer n so that triple_riffle_repeat(list(range(m)),n) == list(range(m)) Discuss, with evidence, the outputs of your function period for different values of m, writing your answer as a comment.
- Implement a technique that compresses strings in a basic way by counting repeated characters. The string aabcccccaa, for instance, would become a2blc5a3. Your function should return the original string if the "compressed" string did not end up being any smaller than the original string. You can assume that the string only contains letters in upper- and lowercase (a–z).Refine the is_palindrome function to work with arbitrary strings, by ignoring non-letter characters and the distinction between upper- and lowercase letters. For example, if the input string is "Madam, I’m Adam!" then you’d first strip off the last character because it isn’t a letter, and recursively check whether the shorter string "Madam, I’m Adam" is a palindrome. c++Implement function rotate that takes a string argument s and an integer argument n, and rotates the string s to the left by n times. For example, the code char s[] = "systems"; rotate(s, 3); will change s into "temssys", while the code char t[] = "abcd"; rotate(t, 1); will change t into "bcda". void rotate(char *w, int j)
