Hello
I have a pretty simple problem
ex:
@a=qw( 1 2 3 4 5 6 7 );
$b=5;
now i just want to check if the value of $b i.e 5
exists in the array @a or not
Q 1) is there any way other than looping through the
array?
Q2 ) is there any predefined function to check the
existance of the element in the array..
thanks in advance
