- The following functions are all intended to check whether a string representing a dna sequence contains any characters that are not 'a','c','g','t', 'A', 'C', 'G', or 'T'. At least some of these functions are wrong. Which ones are correct? A) def valid_dna1(dna): for c in dna: if c in 'acgtACGT': return True else: return False B) def valid_dna3(dna): for c in dna: flag = c in 'acgtACGT' return flag C) def valid_dna4(dna): for c in dna: if not c in 'acgtACGT': return False return True -------------------------------------------------------------------------------------------------------------------------------------------------------- valid_dna1 only valid_dna4 only None of them. valid_dna1, and valid_dna4 onlyPlease design another function called: multiply_up (int n), which will multiple up from 1 to n, like 1*2*3*4*5....*n, and return the result.Here is the assignment Write a program that prints the multiplication table but inserts a randomly generated incorrect value between 1 and 50 into a cell whose row and column are randomly selected. Make sure the program does insert an incorrect value. For example, if row and column of 3 and 4 are randomly selected, keep generating a random number to print for that location until it's not the right value of 12. Then, ask the user to tell where in the table the incorrect number is located by entering the row and column of the incorrect number. Print whether the user was right or not. If he or she was right, ask for and read the correct value; if not, the program must give the correct location and the correct number. My main issue: is how to set up the multiplication table? I've only learned the basics in C++ (loops and if statements).
- The following functions are all supposed to count how many times a certain base (represented as a character variable in Python) appears in a dna sequence (represented as a string variable in Python): def count1(dna, base): i = 0 for c in dna: if c == base: i += 1 return i def count2(dna, base): i = 0 for j in range(len(dna)): if dna[j] == base: i += 1 return i def count3(dna, base): match = [c == base for c in dna] return sum(match) def count4(dna, base): return dna.count(base) def count5(dna, base): return len([i for i in range(len(dna)) if dna[i] == base]) def count6(dna,base): return sum(c == base for c in dna) ======================================================================================= Which of them is correct? count 3, and count 6 only count 1, count 3, and count 4 only All of them are correct. count 1, count 3, count 4, and count 6 onlyThe following functions are all supposed to count how many times a certain base (represented as a character variable in Python) appears in a dna sequence (represented as a string variable in Python): def count1(dna, base): i = 0 for c in dna: if c == base: i += 1 return i def count2(dna, base): i = 0 for j in range(len(dna)): if dna[j] == base: i += 1 return i def count3(dna, base): match = [c == base for c in dna] return sum(match) def count4(dna, base): return dna.count(base) def count5(dna, base): return len([i for i in range(len(dna)) if dna[i] == base]) def count6(dna,base): return sum(c == base for c in dna) Which of the correct functions defined in the above exercise is the fastest? Hint. You will need to generate a very large string to test them on, and the function clock() from the time module to time each function. count2 count3 count5 count4Assume the parameters in the following code are being passed by reference. What numbers reside in the variables a and b after the swap takes place? Next, assume the parameters are being passed by value-result. What numbers reside in the variables a and b after the swap takes place this time? void swap(int x, int y, int z){ int tmp = x; x = y; y = z; z = tmp;} int main(){ int a = 3; int b = 4; swap(a, b, b);}
- The ceiling of a floating-point number x is the smallest integer that is still larger than or equal to x. Alternatively, the ceiling of a floating-point number x is what you get when you round x up to the nearest integer. For example, the ceiling of 2.1 is 3, the ceiling of 0.9 is 1, the ceiling of -4.5 is -4, etc. Write a function called ceiling() to compute the ceiling of a float input parameter that returns one integer value. You may not use python’s ceil() or floor() functions. Your function may use int()/float() functions, and the floor division operator (i.e., '//').Q2: Write a JavaScript function that accepts a number from a user as input and checks if the number is prime, then print True if the number is not a prime, print False. Note: A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself.Write the output of the following code segment along with the justifications:
- Which one of these functions will always return the highest number stored in the array passed to it?Group of answer choices static int max(int[] a){ int m = a[0]; for(int num : a) if (num > m) m = num; return num;} static int max(int[] a){ int m = a[0]; for(int num : a) if (num > m) m = num; max = m;} static int max(int[] a){ int m = a[0]; for(int num : a) if (num > m) m = num; return m;} static int max(int[] a){ int m; for(int num : a) if (num > m) m = num; return m;} static int max(int[] a){ int m = a[0]; for(int num : a) if (num > m) return num; return m;}Edit the isPrime function so that it returns False when any number less than 3 is passed (including negative numbers). Then write a function called nPrimes that accepts an integer parameter called n and then prints the first n prime numbers. Start looking for prime numbers at 3, and keep looking until you find n of them. Your nPrimes function should use the isPrime function to determine if a number is prime. Both of these functions should be placed in a file called NPrimes.py. Here is a sample run of the completed program: Enter the number of primes you want to find: 10 3 5 7 11 13 17 19 23 29 31 from NPrimes import nPrimesdef main(): n = int(input("Enter the number of primes you want to find: \n")) nPrimes(n) main() def isPrime(num): prime = True for x in range(2, num): if num % x == 0: prime = False break return prime;For each expression in the left-hand column, indicate its value in the right-hand column. Be sure to list a constant of appropriate type (e.g., 7.0 rather than 7 for a double, Strings in "quotes"). Expression Value (int) 9.0/2 23 % 5 - (16 % 10) 1.5 * 2 - 6 / 4 “1”+1 (2+3)+”Hello”+4+2*3 23456/100%10 “a”+4-2
