- Write a function named `pairs(a,b,c,d)` that takes four integers as its input and checks whether the sum of any two of these integers is equal to the sum of the other two. If so, the function RETURNs this sum. Otherwise, it RETURNs -1. For example, `pairs(1,2,3,4)` should return 5, because 1 + 4 = 2 + 3 = 5. Another example, `pairs(11,22,13,20)` should return 33, because 11 + 22 = 13 + 20 = 33. Another example, `pairs(1,2,3,5)` should return -1, because no such two pairs exist among these numbers. """ def pairs(a,b,c,d): # remove the following line to solve this question returnCode in Python Write a function, print_integers_less_than(n), which takes an integer parameter n and prints each integer k which is at least 0 and is less than n, in ascending order. Hint: use a simple for loop. For example: Test Result print_integers_less_than(2) 0 1 print_integers_less_than(5) 0 1 2 3 4 print_integers_less_than(-3)Write a function that asks the user how many Fibonacci num-bers to generate and then generates them. Make sure to ask the user to enter the numberof numbers in the sequence to generate. The Fibonacci sequence is a sequence of num-bers where the next number in the sequence is the sum of the previous two numbers inthe sequence. The sequence looks like this: 1, 1, 2, 3, 5, 8, 13,You could assign your input integer to a variable num by num = int (input ("Howmany numbers that generates?: "))• You have to consider exceptions, such as the input integer is zero, negative num-bers or floats.• Please submit your code and console screenshots to Bartleby. Code contain-ing syntax error will be graded zero.• Example: The prompt asks "How many numbers that generates?" If your input is10, then the function will return a list of 10 integers 1, 1,2,3,5,8, 13, 21, 34, 55
- Write a 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”) returns “CAT”subsequence(“CAAAT”, “CAT”) returns “CA”subsequence(“CCG”, “TTA”) returns “”subsequence(“AATGTTACCC”, “AATCTTACCT”) returns “TTACC”subsequence(“AATCTTAGCC”, “AATCAAAGCC”) returns “AATC”If there are multiple subsequences of the same length, then return the firstWrite a DECIMATOR function that takes a unit of character and minimizes it (i.e. removes the last 1/10 of characters). Always zoom in: if a bullet unit has 21 characters, 1/10 of the characters will be 2.1 characters, so DECIMATOR removes 3 characters. DECIMATOR is not kind! Examples decimator ("1234567890") 12 "123456789" # 10 characters, taken out 1. decimator ("1234567890AB") # 12 characters, 2 are released. "1234567890" decimator ("123") "12" # 3 characters, taken out 1. decimator ("123456789012345678901") # 21 characters, issued 3. Solve in Ruby "123456789012345678"Write a program in python with a function repeatPhrase(phrase, n), which prints the given phrase n times, alternating between lowercase and uppercase. For example, repeat('The sky is yellow', 5) would print: the sky is yellow THE SKY IS YELLOW the sky is yellow THE SKY IS YELLOW the sky is yellow Use the function in a program where you ask the user for the phrase and the value of n
- A company wants to transmit data over the telephone but is concerned that its phones may b tapped. It has asked you to write a program that will encrypt the data so that it may be transmitted more securely. All the data transmitted is 4 digit integers. Your program should read a four digit integer entered by the user and calls a function encrypt which takes four digits as arguments and encrypt it as follows . Replace each digit with the result of adding 4 to the digit and getting the remainder after dividing the new value by 10. . Calls another function swap which swaps the first digit with the third, and second digit with the fourth using pass by reference. Then it prints the encrypted integer.This code is for Python Write a program that reads text from the user and reverses the order of every number that appears in the text. For example: Hello! The number is 17. will become Hello! The number is 71. To help with this problem, first write a function rev(text) that takes a string of text and returns the reverse. For example, rev("Oranges") would return 'segnaro". You may create any addition function you need. You must create the rev function. Your program will ask for a string of text and reverse and number. A number is defined as any sequence of digits 0-9. Remember to use if name=="_main": so that ZyBooks can test your rev function. Here are two examples. Welcome to Digit Flipper Enter Some Text: Hello! The number is 17. Revised String: Hello! The number is 71. The input may not have any spaces at all to break up the text. Welcome to Digit Flipper Enter Some Text: a123bb456bbsdfjhskdjh987sss1928 Revised String: a321bb654bbsdfjhskdjh789sss8291Write a function that parses a binary number as a string into a decimal integer. Use the function header:def binaryToDecimal(binaryString):For example, binary string 10001 is 17 (1 x 24 + 0 x 23 + 0 x 22 + 0 * 2 + 1 =17)So, binaryToDecimal("10001") returns 17.Write a test program that prompts the user to enter a binary string and displays the corresponding decimal integer value.
- Write a function count_evens() that has four integer parameters, and returns the count of parameters where the value is an even number (i.e. evenly divisible by 2). Ex: If the four parameters are: 1 22 11 40 then the returned count will be: 2 Hint: Use the modulo operator % to determine if each number is even or odd. Your program must define the function:count_evens(num1, num2, num3, num4) python # Define your function here if __name__ == '__main__': num1 = int(input()) num2 = int(input()) num3 = int(input()) num4 = int(input()) result = count_evens(num1, num2, num3, num4) print('Total evens:', result)Write a function that sums all the numbers of the major diagonal in an nxn matrix of integers using the following header:def sumMajorDiagonal(m):The major diagonal is the diagonal that runs from the top left corner to the bottom right corner in the square matrix. Write a test program that reads a 4x4 matrix and displays the sum of all its elements on the major diagonal.Create a function that returns true if there's at least one prime number in the given range (n1 to n2 (inclusive)), false otherwise. Examples primeInRange (10, 15) true // Prime numbers in range: 11, 13 primeInRange (62, 66) false // No prime numbers in range. primeInRange (3, 5) → true // Prime numbers in range: 3, 5 Notes n2 is always greater than n1. n1 and n2 are always positive. • 0 and 1 aren't prime numbers.
