Write your own version of the SNAP "contains" block, which takes a list and avalue as arguments and reports true if the value is anywhere in the list and reports false otherwise. You should NOT use the existing "contains" block in your implementation.2. Write a custom block called "index of" that takes a list and a value as arguments and reports the index at which the value is found in the list, if it is there. If the value is not present anywhere in the list, report -1.3. Write a custom block called "first e-word" that takes a list as an argument and reports the first word in the list that starts with the letter 'e'. If no such word exists, report a blank (nothing).4. BONUS: Write a custom block called "first word that starts with" that takes a list and a letter as arguments, and reports the first word in the list that starts with the given letter. If no such word exists, report a blank (nothing).

return

Runs the tests in the given suite and throws an error if any fail. If the this block finished without error, then all tests passed. Use (make test suite ...) to build a test quite. Enables strict list bounds checking before running.

Run a single test. If this block completes without error, then the test passed, otherwise this block will throw an error that includes: - a description of the test - the expected result - the actual result Use (make test ...) to create a test.

errorlistTest case expected but got Create a test. expr - an unevaluated expression to be evaluated when the test is run expected - the expected result of evaluating expr description - a text string to identify the test

Create a test suite from one or more tests. Use (make test ...) to create tests.

Check if the given object is a test case.

Populate the given variables with the contents of the given test case.

expr2expected3desc4Convert a list (of numbers) to a text string of the form (list 1 2 ...)

Convert a list to a text string with each item separated by the given delimiter.

Enable (or disable) strict bounds checking on list operations.
