And as most of the execution time is taken by actual work (instead of waiting), and the work in a computer is done by a <abbr title="Central Processing Unit">CPU</abbr>, they call these problems "CPU bound".

---

Common examples of CPU bound operations are things that require complex math processing.

For example:

    testRotate(new long[] {1}, 0, 0, 1, new long[] {1});
    testRotate(new long[] {1}, 1, 0, 1, new long[] {1});
    testRotate(new long[] {1}, 1, 1, 1, new long[] {1});

    // Rotate the central 5 elements, leaving the ends as-is
    testRotate(new long[] {0, 1, 2, 3, 4, 5, 6}, -6, 1, 6, new long[] {0, 2, 3, 4, 5, 1, 6});
    testRotate(new long[] {0, 1, 2, 3, 4, 5, 6}, -1, 1, 6, new long[] {0, 2, 3, 4, 5, 1, 6});

    testRotate(new short[] {1}, 0, 0, 1, new short[] {1});
    testRotate(new short[] {1}, 1, 0, 1, new short[] {1});
    testRotate(new short[] {1}, 1, 1, 1, new short[] {1});

    // Rotate the central 5 elements, leaving the ends as-is
    testRotate(new short[] {0, 1, 2, 3, 4, 5, 6}, -6, 1, 6, new short[] {0, 2, 3, 4, 5, 1, 6});
    testRotate(new short[] {0, 1, 2, 3, 4, 5, 6}, -1, 1, 6, new short[] {0, 2, 3, 4, 5, 1, 6});

이 시나리오에서 (여러분을 포함한) 각 청소부는 프로세서가 되어, 맡은 일을 수행합니다.

그리고 실행 시간의 대부분이 기다림이 아니라 실제 작업에 쓰이고, 컴퓨터에서 작업은 <abbr title="Central Processing Unit - 중앙 처리 장치">CPU</abbr>가 수행하므로, 이런 문제를 "CPU bound"라고 부릅니다.

CPU bound 작업의 흔한 예시는 복잡한 수학 처리가 필요한 것들입니다.

예를 들어:

* **오디오** 또는 **이미지** 처리
