Which of the following pairs of variables label the same node of the DAG? a) t and u b) r and s c) w and y d) t and s Compiler Design compiler-design code-optimization directed-acyclic-graph test-series + – __ asked Sep 2, 2016 edited Jul 16, 2022 by Anjana5051 __ 554 views answer comment Share Follow See all 0 reply Please log in or register to add a comment.
