创建一个稀疏数组 int[][] array2 = new int[sum+1][3]; //之所以行数为有效值个数加 1 是因为需要多加 1 行记录行总数、列总数、有效值个数。固定 3 列 //多出来的 1 行用用以下代码赋值记录行总数、列总数、有效值个数 array2[0][0] = 11; array2[0][1] = 11; array2[0][2] = ...
In particular, in a numeric expression equivalent values can be substituted for one another without changing the result of the expression, meaning changing the equivalence class of the result of the expression. Notably, the built-in == operation on floating-point values is not an equivalence relat...

在上面的代码中,我们首先定义了一个整型数组array,然后使用一个for循环遍历数组并将所有元素的值相加得到sum。最后,通过将sum除以数组的长度得到平均值average,并将其打印出来。 你也可以将上述代码封装为一个方法,这样可以重复利用: public class AverageCalculator { public static double calculateAverage(int[] array...
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。
