Give the answer in kotlin The app should allow the user to select either Fahrenheit-to-Celsius or Celsius-to-Fahrenheit conversions. No other conversion selections should be allowed, and one conversion must be selected at any given time (no situation where no conversion is selected). Your Activity must use a Constraint Layout Use the following formulae for conversion: o T(C) = (T(F) 32.0) 5.0/9.0 o T(F) = (T(C) 9.0/5.0) + 32.0 The initial temperature value should be entered by the user. Pressing a Convert button should calculate the converted temperature value and display it on the screen. Converted values should be displayed out to 1 decimal place only. The conversion operation, value, and calculated results are added to the history: o Example: F to C: 55.0 12.8 C to F: 3.5 38.3 The app must look and act consistently in either portrait or landscape orientation. Concepts and practices discussed in class must be followed.
