Mastering Left Recursion Elimination in Compiler Design for LL(1) Parsing ⚙️

Elimination of Left Recursion|Compiler Design | CFG | LL(1) Parse Left Recursion(LR): A Production of form- 𝐴 → 𝐴𝛼 /𝛽 is called as left recursion. Hence eliminate left recursion, by adding production rules, such that 𝐴 → 𝛽𝐴' 𝐴' → 𝛼𝐴' /∈ General rule: 𝐴 → 𝐴𝛼1 /𝐴𝛼2 /𝐴𝛼3 / …/ 𝛽1 / 𝛽2 /𝛽3 … Hence eliminate left recursion, by adding production rules, such that 𝐴 → 𝛽1𝐴 ′/ 𝛽2 𝐴 ′/𝛽3𝐴 ′ … 𝐴 ′ → 𝛼1𝐴 ' /𝛼2𝐴 ′ /𝛼3 𝐴 ′ … / € Courses playlists: DISCRETE MATHEMATICS: https://www.youtube.com/playlist?list=PLS6nugESt9lLeVTXWMD_NXNVAKAC8RYDg THEORY OF COMPUTATION (TOC): https://www.youtube.com/playlist?list=PLS6nugESt9lJXt7UEXhQTyofeSrqQfPO3 DESIGN AND ANALYSIS OF ALGORITHMS (DAA)| ALGORITHM: https://www.youtube.com/playlist?list=PLS6nugESt9lJ2rluFZTYq8YnpRD1rm5Wf SYSTEM PROGRAMMING (SP): https://www.youtube.com/playlist?list=PLS6nugESt9lIGSB_qxapdJh46j_5Hwhlq DATA STRUCTURE: https://www.youtube.com/playlist?list=PLS6nugESt9lK1S3GnkUFVw5srnSYZPXDo #compilerDesign #compiler #shorttricks #cseacademy #cfg #cd #first #follow #ahmadsir #btech #btechcse #gatecse #engineering #pk #university
