NettetLinear search is a method for searching a value within an array. It sequentially checks one by one of the arrays for the target element until a match is found or until all the elements have been searched of that array. Why is the linear search also called sequential search? NettetIn Perl, subroutines or functions are created or declared using the “sub” keyword before the subroutine name which is given to the set of logical code that is reused in the program and in Perl, the Perl compiler first compiles the program and then executes it irrespective of declaration of subroutines or functions.
