1. A pushdown automaton reads a given input string from left to right. 2. Input strings that the template cannot format are returned unaltered.3. The parsing of the input string proceeds as follows. 4. The third algorithm is to match the pattern against the input string by backtracking. 5. The first symbol from the input string that the parser sees is'1 '. 6. It accepts any number of input strings . 7. All finished now . " Additional testing with various other input strings bears out this conclusion. 8. This template checks whether any given input strings are valid speedy deletion ( CSD ) criteria. 9. It is also possible to compare the input strings to a custom selection of CSD criteria. 10. Every Turing machine computes a certain fixed partial computable function from the input strings over its alphabet.
