Explanation of Solution
Definition of Left factoring:
Left factoring is used when the parser has to choose between the RHSs of a non-terminal while expanding a non-terminal, where there are multiple RHS for the same non terminal starting with the same terminal symbol.
Example:
A aB / a
This production cannot pass the pairwise disjoint test as

Then, the program reads the matrix and finds the index of the even and odd numbers and display them with their corresponding indices. Use adequate messages during the program execution.arrow_forward#Solve it with C programing Suppose, you are working as a Data Entry Operator in a company. You have created a dataset that contains the names of N employees. Then your supervisor wants you to look for a particular employee by name. (Consider, every name in the data set is unique).Now your task is to write a program which will help you to find out the name which your supervisor is looking for.If found then print a message "Matched" otherwise print "Not Matched". (N.B: Without quotation) The first line of input will take an integer (N) which indicates the number of names in the dataset. Then the second line will take N space-separated strings. The third line of input will take another string as search value. Sample input:5rabbe sharif shazzad polash tutulsharif Sample output:Matched Sample input:4jahid nishat rasel shakibmunna Sample output:Not Matchedarrow_forward
- User-defined ordinal data types: pros and cons? Associative arrays have pros and cons, which are discussed below.arrow_forwardHow is memory allocated for arrays as opposed to linked lists?arrow_forwardISBNThis problem is slightly more difficult than the above problem. This one requires a data type that stores 10 digits. BackgroundPublishers and bookstores use a number system called the International Standard Book Number (ISBN) system to identify books. At the start of publication, each book is assigned a unique ISBN. An ISBN, once assigned, can never be re-used. Click here for detailed information on this numbering system.An ISBN consists of exactly 10 digits. The rightmost digit is the check digit. The check digit is validated modulo 11.• multiply each digit from the first to the ninth by a weight from 10 to 2 respectively (the first digit by 10, the second by 9,.., the ninth by 2).• the sum of the products plus the check digit should be divisible without remainder by 11.• if there is a remainder, the whole number is not a valid ISBN SpecificationsDesign a program that validates an ISBN. Your program keeps accepting a whole number and determining if that whole number is a valid…arrow_forward
