For this exercice, you will need to write a method that asks for $10$ numbers from the user in the main method. These numbers represent $10$ students' grade. Once the $10$ numbers are obtained, you will need to call the four other methods passing the $10$ numbers as an argument and print the results from the main. The method calculateAverage needs to calculate and then return the average of the grades. The method calculateMedian calculates and returns the median of the grades. The method calculateNumberFailed calculates and returns the number of students that failed and calculateNumberPassed calculates and returns the number of students that passes. Grades are numbers between $0\mathrm{.}0$ and $100\mathrm{.}0.$ The passing grade is $50\%.$ Note that calculateAverage, calculateMedian, and calculateNumberPassed should all work for arrays of arbitrary lengths $($and not necessarily $10).$
