Explanation:
Detailed explanation-1: -Step 1: Find all nullable non-terminal variables which derive first. Step 2: For all the productions of X → a, construct all production X → a, where a is obtained from x by removing non-terminals from the first step. Step 3: Combine the result of the second step with the original production.
