An array is defined to be twin paired if its even$-$valued elements $($if any$)$ are in ascending order and its odd$-$valued elements $($if any$)$ are in ascending order.

The array $\{-6,12,1,24,3,5\}$ is twin paired because the even$-$valued elements $(-6,12,24)$ are in ascending order and so are the odd$-$valued elements $(1,3,5).$ However, the array $\{3,2,1\}$ is not twin paired because the odd numbers are not in ascending order.

Write a function named isTwinPaired that returns $1$ if its array argument is twin paired, otherwise it returns $0.$

If you are programming in Java or C#$,$ the function signature is

int isTwinPaired$($int$[]$ a$)$

If you are programming in C or C$++,$ the function signature is

int isTwinPaired$($int a$[],$ int len$)$ where len is the number of elements in a$.$

Other twin paired arrays include:

$\{2,4,32\},$

$\{2,2,2,1,1,1\},$

$\{1,19,23\},$

$\{1,2\},$

$\{2,1\},$

$\{8\},$

$\{17\},$

$\{\}$
