Competitive Programming Workshop for Beginners | Day 4: Prefix Sum & Two Pointer | IEEE CS LU SBC

Welcome to Day 4 and the final session of the Competitive Programming Workshop for Beginners, organized by the IEEE Computer Society Leading University Student Branch Chapter. In this session, Swadheen Islam covers two useful problem-solving techniques in competitive programming: Prefix Sum and Two Pointer. Topics Covered: Introduction to Prefix Sum Building and using Prefix Sum arrays Range sum problems Introduction to the Two Pointer technique Common applications of Two Pointer Using these techniques in competitive programming problems This session focuses on helping beginners understand how Prefix Sum and Two Pointer can be used to solve certain problems more efficiently and reduce unnecessary computation. Session Details Class: 04 Topic: Prefix Sum & Two Pointer Instructor: Swadheen Islam Date: 22 August 2026 Workshop: Competitive Programming Workshop for Beginners As we conclude the workshop, we hope this session helps you understand how these techniques can be applied in problem solving. We also hope the four-day workshop has given you a useful starting point and a clearer direction for continuing your Competitive Programming journey.
