Concept: Each element in an array is a one-dimensional array, and the array is called a two-dimensional array.静态初始化：Static initialization:动态初始化：Dynamic initialization:注：其中列个数可以省略不写，因为Java中的二维数组存在不规则矩阵这样的数组，因此写了也没有多大意义。Note: The number of...
public static void swapArray(int[] arr1,int[] arr2){ int[] temp; temp = arr1; arr1 = arr2; arr2 = temp; } // 在main中,两个数组的值并没有发生交换,也就是说在swapArray中数组的地址虽然交换了,但是原本数组的地址并未发生交换 1. 2. 3. 4. 5. 6. 7. 结论:Java当中只存在值传递...

In computer science, the maximum sum subarray problem is the task of finding a contiguous subarray with the largest sum, within a given one-dimensional array A[1...n] of numbers. Formally, the task is to find indices and with, such that the sum is as large as possible. ...
