WebAn algorithm to process infix notation could be difficult and costly in terms of time and space consumption. Prefix Notation. In this notation, operator is prefixed to operands, i.e. operator is written ahead of operands. For example, +ab. This is equivalent to its infix notation a + b. Prefix notation is also known as Polish Notation. There are two key algorithms for computing a prefix sum in parallel. The first offers a shorter span and more parallelism but is not work-efficient. The second is work-efficient but requires double the span and offers less parallelism. These are presented in turn below. Hillis and Steele present the following parallel prefix sum algorithm:
