Write a MATLAB program that will curve a grade entered by the user. The grade should be read from the user and should be an integer with $0$ being the minimum grade and $100$ being the maximum grade. The program should display the entered grade and the curved grade. The instructor who will use this program is a bit odd and desires the following curving scheme: if the grade is in the range of $0$ to $60$ curve by $-5,$ if the grade is in the range of $61$ to $85$ give no curve, and if the grade is in the range of $86$ to $100$ curve by $+5.$ Verify the operation of the program by testing it for the grades: $27,60,80,86,$ and $98.$ Hint: this should be solved using if$-$else statement$($s$)$ and not a swi XN$11$ tch$-$case statement.
