AVG():选择若干表列的平均值。 SUM():允许为一个数值列共选择。 ARRAY():数组聚合函数把输入值,包括空值,串连成一个数组。 1. 2. 3. 4. 5. 6. 7. 数字函数:PostgreSQL的函数需要在SQL来操作数字的完整列表。 字符函数:PostgreSQL函数在PostgreSQL需要对字符串进行操作的完整列表。 这里附上自己写着写着...
log1p(double x) Returns the natural logarithm of the sum of the argument and 1. static double max(double a, double b) Returns the greater of two double values. static float max(float a, float b) Returns the greater of two float values. static int max(int a, int b) Returns the gre...
This is interesting because it is implemented using RecursiveAction, the fork/join task that does not yield values on join()method invocations. Instead, tasks share mutable state: the array to be sorted. Again, experiments show a near-linear speedup in the number of cores. Conclusion This ...

To make this more concrete, suppose the rod was length 4, the values were l1 = 2, l2 = l3 = l4 = 1, and each piece has the same worth regardless of length. Then, if we make our first cut in the middle, we have that the optimal solution for the two rods left over is to ...
Performs parallelPrefix(double[], DoubleBinaryOperator) for the given subrange of the array. static void parallelPrefix(int[] array, IntBinaryOperator op) Cumulates, in parallel, each element of the given array in place, using the supplied function. static void parallelPrefix(int[] array, int fr...
