program (using Java or Python) for converting binary numbers to decimal numbers, and conversely. [You can not use the conversion functions from the mathematical library.] Your program should do the following: Ask the user if they want a Binary number converted to Decimal number, a Decimal number converted to a Binary number, or to quit the program. Ask the user for the number, take the appropriate action and then print out the appropriate message

In python >>> play_nim(10) The goal is 10. Pick a number between 1 and 3 Current Score 0. Player 1 enter a number: 1 Current Score 1. Player 2 enter a number: 2 Current Score 3. Player 1 enter a number: 9 Invalid number, try again. Current Score 3. Player 1 enter a number: 1 Current Score 4. Player 2 enter a number: 3 Current Score 7. Player 1 enter a number: 3 1 >>> play_nim(4) The goal is 4. Pick a number between 1 and 3 Current Score 0. Player 1 enter a number: 3 Current Score 3. Player 2 enter a number: 3 2 >>> play_nim(21) The goal is 21. Pick a number between 1 and 3 Current Score 0. Player 1 enter a number: 0 Invalid number, try again. Current Score 0. Player 1 enter a number: -78 Invalid number, try again. Current Score 0. Player 1 enter a number: 3 Current Score 3. Player 2 enter a number: 2 Current Score 5. Player 1 enter a number: 1 Current Score 6. Player 2 enter a number: 3 Current Score 9. Player 1 enter a number: 2 Current Score 11. Player 2…

Write a program that mimics a calculator. The program should take as input two integers and the operation to be performed. It should then output the numbers, the operator, and the result. For division, if the denominator is zero, output an appropriate message. Limit the supported operations to + -/ *and write an error message if the operator is not one of the supported operations. Here is some example output: 3 + 4 = 7 13 * 5 = 65   C++

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

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.
