Write a java program that prints the product of two selected numbers

from a line

$$ First line of input contains the number of lines to follow

$$ First number of each following line contains the number of integers

$($n$>=4$ and n$<=1000,)$ that follow in the line

$$ Those n integers $($each integer $>=0$; $<=1000)$ follow till the end of the

line $($separated by space$).$ They can be stored $($except the last two$)$ in

an array using index numbers $1...$n$-2($but not necessary$)$

$$ The last two integers x$,$ y $($x$,$y$>=1$ & x$,$y$<=$n$-2)$ in the line is the index

$($starting from $1)$ of the integers from the line to multiply
