Obviously, the data is so small that DFS will inevitably pass
Search by top, bottom, left, and right, and mark the search to avoid repetition.
CodeAs follows:

Louis's two methods are not correct. The first method returns the list order. The second method finally constructs an empty header followed by a value order pair. The list header should be the first element.

The question is to let you find a number in the array that can divide all the numbers in this array. Obviously, if it exists, this number must be the smallest one.

The general idea is that there is an array containing N numbers. You can use the + 1 or-1 operation to make the number 1-N, and there is no repeated number.
In this case, I should try to place the number in the original array to the

It can be said that this question involves many knowledge points and is a good question.
First, this question involves the knowledge of computational ry, finding the horizontal distance between the coordinates of the center and then finding the
Here we will popularize the knowledge of Euler's loop.
Euler's road refers to any point that begins to traverse, and each side passes through exactly once. Such a road is Euler's road.

Computers normally cannot generate really random numbers, but frequently are used to generate sequences of pseudo-random numbers. these are generated by some algorithm, but appear for all practical purposes to be
Coin change
Suppose there are 5 types of coins: 50-cent, 25-cent, 10-cent, 5-cent, and 1-cent. we want to make changes with these coins for a given amount of money.
For example, if we have 11 cents, then we can make changes with one 10-
