In a script file, write a code that finds wheather a given numeric grade, G $($between $0$ & $100),$ is a passing of failing grade then determine the Letter Grade $($LG$)$ corressponding to this given numeric grade.

Start your code by defining the grade as G$=78$

Use the following criteria:

Pass$/$Fail Criterion:

If G$>=70$ status$=$'Passed'

If G$<70$ status$=$'Failed'

Letter Grade:

G $>=90$ LG$=$ A

$80<=$ G $<90$ LG $=$ B

$70<=$ G $<80$ LG $=$ C

$60<=$ G $<70$ LG $=$ D

G $<60$ LG $=$ F

Test your script with one value in each of the $5$ ranges. $(93,86,78,64,57)$ Your final submission should be with G set to $57.$
