Write a program that

$$ First, it asks the user to choose whether sorting order is in increasing order $($I$$ or

$$i$)$ or decreasing order $($D$$ or $$d$)$; if the user inputs other character, quit the

program directly.

$$ Second, it reads three integer numbers and sorts these three numbers in the order

according to the choice from first step.

$$ Last, it reports that three numbers are in lenient or strict increasing$/$decreasing

order. Only when three numbers are all different, the ordering is in strict,

otherwise it is a lenient ordering. Note that when three numbers are all the same,

it is lenient, but it can be lenient increasing or lenient decreasing depending on the

choice from first step
