这里介绍一种实现,Double-Array Trie(双数组字典树),其实它就是双数组,跟树结构没啥关系。他能在一定程度上减少内存的浪费。 两个数组,一个是base[],另一个是check[]。设数组下标为i ,如果base[i], check[i]均为0,表示该位置为空。如果base[i]为负值,表示该状态为终止态(即词语)。check[i]表示该状态的前一状态。 定

Have you considered using vector<double> in place of your dynamically allocated arrays? This would avoid potential allocation/deallocation errors and you could then replace the unchecked array operator with the bounds-checked at() method. Jan 26, 2011 at 4:47am ...

将字节数组转换成int /* This example initializes an array of bytes, reverses the array if the computer architecture is little-endian (that is, the least significant byte is stored first), and then calls the ToInt32(Byte[], Int32) method to convert four bytes in the array to an int. ...
int sz = sizeof(array ) / sizeof(*array); 7. 数组名一般作为该数组的第一个元素的指针:p156 不将数组转换为指针的例外情况: 将数组用于 取地址(&)操作符的操作数 或 sizeof 操作符的操作数时,或者用作对数组的引用进行初始化时,不会将数组转换为指针。
This patch addresses the management of the DoubleVector type in crates: the original approach was to use ReadDoubleArray for crate::CrateDataTypeId::CRATE_DATA_TYPE_DOUBLE_VECTOR but the OpenUSD implementation has a dedicated codepath for it (that does not account for compression or 32bit size...
