can you help me write this code in python and c++ NOte: beginner level

• create a program and a function that takes the level to grade and returns the middle percentage mark

• accept a string type (ex. 4+ or R) as a level and return an integer as the percentage

• Level [1]	Percent [2]
  4+	95% - 100%
  4	87% - 94%
  4-	80% - 86%
  3+	77% - 79%
  3	73% - 76%
  3-	70% - 72%
  2+	67% - 69%
  2	63% - 66%
  2-	60% - 62%
  1+	57% - 59%
  1	53% - 56%
  1-	50% - 52%
  R	0% - 49%

• usually we only place one (1) return statement at the very end of our function, not several inside an if statement

  • if "invalid" input is passed to the function (a string that is not a valid level), then return a "-1"

    • "-1" is commonly used as a return value that means there has been an error
