Question 1: Please develop a program. The program shows a O(n^2) time complexity. You may design nested loops. When you input a number, the output should be how many times of the loops. For example, if your input is 10, the number of loops should be 100 times, 200 times, 300 times, etc. The number of loops do not have to be an accurate number.
In python This assignment assess problem solving ability and the use of the modulo operator, functions, lists and nested loops. The Modulo (%) operator returns a remainder of the two numbers divided. e.g. 9 % 2 will yield a 1 because 9/2 = 4 and the remainder is 1. Write one program that will compute both the Least Common Multiple, and the Greatest Common Factor of two random numbers between 2 and 30. The program will display all factors and multiples of the two numbers. When displaying the multiples of the numbers, only display up to the first input times the second input. Use functions to compute the answers. Loop the program so that the user try again. create the loop so that hitting enter will continue. The example is below: Integer1: 12Integer2: 3 The Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, The Multiples of 12 are 12, 24, 36, The lowest common Multiples is 12 The Factors of 3 are 1, 3, The Factors of 12 are 1, 2, 3, 4, 6, 12, The greatest…

Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…
Using DEV C++, create a program to perform matrix multiplication, and will let the user input two square matrices. With a maximum of 10 x 10 matrices. If the user inputs negative matrices, more than 10 matrices, or 1 matrix the program should display “Invalid.” If the user inputs n = 3 First matrix: -35 54 64 31 45 -12 17 -31 -19 Second matrix: 69 90 -85 29 52 -19 37 -26 -97 Output: 587 9249 14127 -8656 -8711 1326 -6610 14754 14694 If the user inputs n = 2 First matrix: 1 2 3 4 Second matrix: 5 6 7 8 Output: 19 22 43 50

Python program: Write a program that reads an integer between 0 and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all its digits is 14. (Hint: Use the % operator to extract digits, and use the // operator to remove the extracted digit. For instance, 932 % 10 = 2 and 932 // 10=93) Here is a sample run: Enter a number between 0 and 1000: 999 The sum of the digits is 27

Please do it in python I have asked this question before but i need it in try and except You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen. The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k ? k grid consisting only of that character. Input Specification: (Use a try and except here)The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. Use try and except
Task 13 Write a Python program that takes a number and tells how many digits are in that number. [Consider the input number has to be an INTEGER] You are not allowed to use len() function Example: If the user gives 9876, you should print 4. Hint: Keep floor dividing by ten and count how many times this could be divided. 9876 floor divide by 10, is 987, count that got 1 digit (total 1) 987 floor divide by 10, is 98, count that got 1 digit (total 2) 98 floor divide by 10, is 9, count that got 1 digit (total 3) 9 floor divide by 10, is 0, count that got 1 digit (total 4) Done! (When the number becomes 0 your loop should end.)
In Java: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
