Consumers read the item into a local buffer and process it off-line. Both producers and consumers may modify the label. This array need not be in sorted order. The problem is to identify all the significant elements of the array. Present an time algorithm for this problem.
Input is a graph in adjacency matrix form.
The problem is to check if this graph is undirected or not. You can use up to processors, where n is the number of nodes in the graph. Programming Languages Programs in the Java programming language are typically not compiled to native machine code. Explain in detail what is done, and discuss the pros and cons of the approach. Describe, using examples, the conceptual and practical differences between denotational semantics and attribute grammars, as mechanisms for describing the semantics of a programming language.
