1# Sub_string_finder sample 2An example that uses the `parallel_for` template in a substring matching program. The [oneAPI Threading Building Blocks Get Started Guide](https://www.intel.com/content/www/us/en/docs/onetbb/get-started-guide/current/overview.html) describes this example. 3 4For each position in a string, the program displays the length of the largest matching substring elsewhere in the string. The program also displays the location of a largest match for each position. Consider the string "babba" as an example. Starting at position 0, "ba" is the largest substring with a match elsewhere in the string (position 3). 5 6## Building the example 7``` 8cmake <path_to_example> 9cmake --build . 10``` 11 12### Predefined make targets 13* `make sub_string_finder_simple` - builds the example as it appears in the Get Started Guide. 14* `make sub_string_finder_extended` - builds the similar example with more attractive printing of the results. 15* `make sub_string_finder_pretty` - builds the example extended with a sequential implementation. 16* `make sub_string_finder` - builds all sample versions. 17 18## Running the sample 19### Predefined make targets 20* `make run_sub_string_finder` - executes the example with predefined parameters. 21* `make light_test_sub_string_finder` - executes the example with suggested parameters to reduce execution time. 22 23### Application parameters 24Usage: 25``` 26sub_string_finder_simple 27sub_string_finder_extended 28sub_string_finder_pretty 29``` 30 31The example does not requires application parameters. 32
