A program in c++ that accept an integer array and its size as arguments and assign the elements into a 2-D array of integers. for ex: if the array is 1,2,3 The resultant 2-D array is given by
c++中的一个程序，它接受一个整数数组及其大小作为参数，并将元素分配到一个二维整数数组中。对于例:如果数组是1,2,3，则合成的二维数组由
1 2 3

can you please give me the logic
你能给我逻辑吗
The logic is very simple. Let n be the size of the 1D array.
逻辑很简单。设n为一维数组的大小。
create a 2d array of size n x n
for y in [0, n)
copy elements [0, n-y) from the 1D array to line y
set elements [n-y, n) to 0 in line y
...and that's basically it, where [begin, end) denotes a half open range.
…基本上就是这样，(开始，结束)表示半开放的范围。
