The Lexical Analyzer’s job and procedure is to tokenize the programme by dividing it into valid tokens and deleting all white space characters.
Detailed explanation-2: -Lexical Analysis is the first phase of compiler also known as scanner. It converts the High level input program into a sequence of Tokens. Counting all the boxes, the total number of tokens comes out to be 26.
