@gatecse @Arjun Sir longest prefix matching is done for every operator and variable names right? Hence *= is considered as a single token, One followup question is suppose the given expression was something like this :

a -  =   b *     = a; Spaces will be removed by LA phase and then it will result in a–=b*= a; and so 6 tokens right Sir?
