In Python, An acronym is a word formed from the initial letters of words in a set phrase. Write a program whose input is a phrase and whose output is an acronym of the input. If a word begins with a lower case letter, don't include that letter in the acronym. Assume there will be at least one upper case letter in the input. Ex: If the input is: Institute of Electrical and Electronics Engineers the output is: IEEE

13. Implement function triangleArea(a,b,c) that takes as input the lengths of the 3 sides of a triangle and returns the area of the triangle. By Heron's formula, the area of atriangle with side lengths a, b, and c is √ s ( s−a )( s−b)( s−c ) , where s=(a+b+ c )/ 2 .>>> triangleArea(2,2,2)1.7320508075688772
C++ Given a positive integer, N, the ’3N+1’ sequence starting from N is defined as follows: If N is an even number, then divide N by two to get a new value for N If N is an odd number, then multiply N by 3 and add 1 to get a new value for N. Continue to generate numbers in this way until N becomes equal to 1 For example, starting from N = 3 the complete ’3N+1’ sequence would be: 3, 10, 5, 16, 8, 4, 2, 1 Write code to ask the user to enter a positive integer (N) in the main() function. Write a function sequence() that receives the integer value N and display the ‘3N+1’ sequence starting from the integer value that was received (entered by the user). The function must also count and return the numbers that the sequenceconsists of. The returned value must be displayed from the main() function.
1. Write a Python regex pattern that matches a valid email address, assuming that an email address consists of a username, followed by the "@" symbol, followed by a domain name, which in turn consists of one or more subdomains separated by dots, and ending with a top-level domain (e.g., .com, .org, .edu, etc.). 2. Using the re.findall() function in Python, write a Python code snippet that takes the text string and the regex pattern from Q4 and returns a list of all the email addresses found in the string. 3. Suppose you want to modify the regex pattern from Q4 to also match email addresses that contain hyphens ("-") in the username and/or domain name. What changes would you make to the pattern, and why? 4. Using the modified regex pattern from Q6, write a Python code snippet that takes the text string and the modified regex pattern, and returns a list of all the email addresses found in the string. Note: You can assume that the text string contains valid email addresses separated by…
4.16 In Python, Write a program whose input is two integers. Output the first integer and subsequent increments of 10 as long as the value is less than or equal to the second integer. Ex: If the input is: -15 30 the output is: -15 -5 5 15 25 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last.
Python 3.7.4: Write a loop that reads strings from standard input, where the string is either "duck" or "goose". The loop terminates when "goose" is read in. After the loop, your code should print out the number of "duck" strings that were read. ----------------- This is what I tried so far, and it's been marked wrong by MyProgrammingLab: count = 0inputstring=input("Enter goose/duck: ")countducks=0while inputstring!="duck": countducks+=1 inputstring=input("Enter either the word goose or duck: ")print(countducks, "This is the number of times duck was entered:" count)
6.25 In Python, Write a program that gets a list of integers from input, and outputs non-negative integers in ascending order (lowest to highest). Ex: If the input is: 10 -7 4 39 -6 12 2 the output is: 2 4 10 12 39 For coding simplicity, follow every output value by a space. Do not end with newline.
In python, Problem Description:Sheldon and Leonard are physicists who are fixated on the BIG BANG theory. In order to exchange secret insights they have devised a code that encodes UPPERCASE words by shifting their letters forward. Shifting a letter by S positions means to go forward S letters in the alphabet. For example, shifting B by S = 3 positions gives E. However, sometimes this makes us go past Z, the last letter of the alphabet. Whenever this happens we wrap around, treating A as the letter that follows Z. For example, shifting Z by S = 2 positions gives B. Sheldon and Leonard’s code depends on a parameter K and also varies depending on the position of each letter in the word. For the letter at position P, they use the shift value of S = 3P + K. For example, here is how ZOOM is encoded when K = 3. The first letter Z has a shift valueof S = 3 × 1 + 3 = 6; it wraps around and becomes the letter F. The second letter, O, hasS = 3 × 2 + 3 = 9 and becomes X. The last two letters…

Ex: If the input is: -15 30 the output is: -15 -5 5 15 25 (with the end starting a new line.) Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last. creating a new line at the end. (ex: 5 4 3 2 1 )
3.19 In Java Write a program with total change amount in pennies as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies. Ex: If the input is: 0 the output is: No change Ex: If the input is: 45 the output is: 1 Quarter 2 Dimes
Use C++ Write a program that reads a list of integers, and outputs whether the list contains all even numbers, odd numbers, or neither. The input begins with an integer indicating the number of integers that follow. Ex: If the input is: 5 2 4 6 8 10 the output is: all even Ex: If the input is: 5 1 -3 5 -7 9 the output is: all odd Ex: If the input is: 5 1 2 3 4 5 the output is: not even or odd Your program must define and call the following two functions. IsVectorEven returns true if all integers in the array are even and false otherwise. IsVectorOdd returns true if all integers in the array are odd and false otherwise.bool IsVectorEven(vector<int> myVec)bool IsVectorOdd(vector<int> myVec)

Use Sage to program Exercise 5.In 1202 AD, Leonardo Pisano asked the following famous problem:A certain man had a pair of rabbits together in a certain enclosedplace, and one wishes to know how many are created from the pair inone year when it is the nature for of them in a single month to bearanother pair, and in the second month those born bear also. Becausethe abovewritten pair in the first month bore, you will double it. therewill be two pairs in one month. One of these, namely the first, bears inthe second month, and thus there are in the second month three pairs;of these in one month two are pregnant, and in the third month 2pairs of rabbits are born, and thus there are 5 pairs in the month;...Explain how the rabbits reproduce. Create a list F where F[x] is the number ofrabbits in month x. (so F[0]=1, F[1]=2) Find F[12]. Find F[100].
