将43行的return (i + capacity()) % capacity();改为return (i % capacity() + capacity()) % capacity(); 原因:原来的表达式“(i + capacity()) % capacity();”如果i是负数的话,需要保证capacity() >= -i。而更改后的表达式“ (i % capacity() + capacity()) % capacity();” 中的先对i取模相加,最后再取模操作会确保结果是一个非负整数,并且不会超过 capacity() 的值。这是因为取模操作会返回一个在 0 到 capacity() - 1 范围内的数,即使原始的和可能是负数。保证函数index()的传入形参i<-capacity()不会崩溃,且能正确返回 0 到 capacity() - 1 范围内的的索引值。
