In C-Language, In general, we compare each element of the
array in a loop that iterates till the element is found.
This is called Linear search.

while(1)
{
// code here
if(element found)
break;
}

Here, execution time depends on the array size and position
of the element in the array.
For sorted arrays, we can use techniques such as binary
search using which execution is faster.

Answer / palanisaran

my $element = 'Whatever you are searching for' ;
if (grep {$_ eq $element} @TheArray) {
print "Element '$element' found!\n" ;
}
