The Babylonian algorithm to compute the square root of a positive number n is asfollows:1. Make a guess at the answer (you can pick n/2 as your initial guess).2. Compute r = n / guess3. Set guess = (guess +r)/ 24. Go back to step 2 for as many iterations as necessary. The more you repeat steps2 and 3, the closer guess will become to the square root of n.
Write a program that inputs a double for n, iterates through the Babylonian algo-rithm five times, and outputs the answer as a double to two decimal places. Your
answer will be most accurate for small values of n.
Write an algorithm in pseudocode for the following problem:
Write a program that reads a series of daily high temperatures from the keyboard and then prints to the screen the number of days that each high was achieved.
Assume that the temperatures will fall between -40 and 110, inclusive.
You'll print the temperature and then the number of days for each temperature that was the high at least once. So your output will be in two columns.
The key to this is that you'll have an array where the indices of the array represent the temperatures and the contents are the number of days where that temperature was the high.
Numeric Triangle Pattern
Based on the example given on the previous module, create a program that replicated
the triangle pattern shown. Try to look at the examples closely and think of an algorithm
that replicates the outputs. Let's see if you still look at Triangle problems the same way
after this problem.
Input:
Integer value n.
Output:
A triangle based on the inputted value of n.

- Make a program that asks for a width, and then prints a pyramid of that width. The pyramid must be of odd width, and if the user enters an even number the program should print "Please enter an odd number" and ask again. (It is ok if the program gives an error if the user enters a non-number). Example: Please enter the pyramid width 10Please enter an odd numberPlease enter the pyramid width 14Please enter an odd numberPlease enter the pyramid width 13 * *** ***** ******* ********* ************************ The first line should have 1 asterisk, the second 3, then 5, 7, 9 etc. The number of spaces before starting the asterisks is (n−i)/2 Where n is the width of the pyramid and i is the number of asterixes in the current line. Note that this is always a whole number, as n and i are odd and hence (n-i) is even.arrow_forwardWrite a program that calculates the equivalent resistance of a circuit. n electrical resistors with resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied across each. Their equivalent resistance Reg is related to the values R1, R2, ..., Rn by: 1 1 1 1 + +...+ R R R, R. "eq Write a program that prompts the user to enter the resistance of n resistors. The user should be prompted continuously by using a while loop until a zero or negative value is entered (the program should count the number of resistors n entered by the user and store the values in an array). Use another separate loop to print the resistance values entered by the user and the equivalent resistance Reg. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.arrow_forwardA regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is Area = ( n * s2 ) / (4 * tan( π/n) Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area.arrow_forward
- A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program whose input is a word or phrase, and that outputs whether the input is a palindrome. Ex: If the input is: bob the output is: palindrome: bob Ex: If the input is: bobby the output is: not a palindrome: bobby Hint: Start by just handling single-word input, and submit for grading. Once passing single-word test cases, extend the program to handle phrases. If the input is a phrase, remove or ignore spaces. 367012.2549490.qx3zqy7 LAB 5.25.1: LAB: Palindrome 6/ 10 АCTIVITY LabProgram.java Load default template... 1 import java.util.Scanner; 2 3 public class LabProgram { public static void main(String[] args) { 4 Type your code here. */ } 7 } 8arrow_forwardA palindrome is a word or a phrase that is the same when read both forward and backward.
