一切看起来都很简单，但有些事情并没有想到一个正常的解决方案。基本代码：

M = 5
KTR(2 * M, 2 * M)
FOR i = 1 TO M - 1: FOR j = i + 1 TO M: KTR(i, j) = 1

蟒蛇代码：

M = 5
KTR = [[None] * (2 * M), [None] * (2 * M)]
z = 1
z1 = z + 1
for i in range(M - 1):
    for i1 in range(M):
        KTR[0][z] = 1
        KTR[1][z1] = 1
        z = z + 1
        z1 = z1 + 1

但是，总是有越界调用。告诉我我做错了什么。这不是学校或大学的问题，我希望将程序重新制作成另一种语言。

初始化音频

    SoundPool sp;
    int error_sound;
    int del_sound;
    int level_complete_sound;
    int level_complete_123;



    // Аудио
    sp = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);

    error_sound = sp.load(this, R.raw.error_sound, 1);
    del_sound = sp.load(this, R.raw.del_sound, 1);
    level_complete_sound = sp.load(this, R.raw.level_complete_sound, 1);
    level_complete_123 = sp.load(this, R.raw.level_complete_123, 1);

然后我在按下时重复使用一种或另一种声音

sp.play(error_sound, 1, 1, 0, 0, 1);

一切正常，但偶尔，尤其是当活动重新启动时，声音通过一个，并发生错误

E/AudioMixer: AudioMixer::getTrackName out of available tracks
E/AudioFlinger: no more track names available
E/AudioFlinger: createTrack_l() initCheck failed -12; no control block?
E/AudioTrack: AudioFlinger could not create track, status: -12
E/SoundPool: Error creating AudioTrack

音频文件的大小和持续时间都很小，大约为 3-6 秒。据我了解，错误本身表明由于内存不足而无法加载曲目。但我不明白我到底做错了什么。请告诉我。
