Contributions summary:Grigorii primarily focused on implementing new operators within the rxcpp library. They added `min` and `max` operators, as well as `distinct`, `element_at`, `sample_with_time`, `ignore_elements`, `debounce`, `exists`, `contains`, `all`, `timestamp`, `take_last`, `skip_last`, and `time_interval`. Their contributions involved writing test cases for these operators, covering various scenarios and edge cases to ensure their correct functionality within the reactive programming framework.
