Why are LR parsers a better option than LL parsers?  Group of answer choices All these options are correct LR parsers can be constructed to recognize nearly all programming-language constructs for which CFGs exist. LR-parsing is the most general non-backtracking, shift-reduce method known, yet can be implemented relatively efficiently. LR parsing can detect a syntactic error as soon as possible

Time Complexity

In computer science, the computational complexity that is measured in terms of time is referred to as time complexity that defines how long it takes a computer to execute an algorithm. An algorithm's time complexity is measured by the the amount of time required to execute each statement of code in the algorithm. If a statement is set to execute repetitively, the number of times it will be N multiplied by the time it takes to run that function each time is equal .
