Given an input string, reverse the string word by word. A word is defined as a sequence of non-space characters.The input string does not contain leading or trailing spaces and the words is always separated by a single space.For example,Given s = " the sky is blue ",Return " blue is sky the ".Could do it in-place without allocating extra space?1, the beginning of the idea is to find the first and last word, and then exchange them two, but the problem is that two words of inconsistent length will

will have a second time complexity.
A more efficient algorithm has been found. Using the rotating jamming case, we can update the data in real time within the constant time, instead of re-calculating the endpoint.In fact, considering a convex polygon, there are two pairs andXAndYTangent tangent to the last four endpoints. The four lines have determined the external rectangle of a polygon. However, unless a polygon has a horizontal or vertical edge, t

Question: Find the maximum diameter of the convex hull.
Http://poj.org/problem? Id = 2187
First, evaluate the convex hull of a polygon.
Then, the maximum diameter is obtained by rotating the jamming case.
In fact, two parallel lines are clamped out of the convex hull and rotated.
If Pa and Pb are the farthest points, then the parallel line o

Js + css3 achieve a pair of rotating eyes ------- Day68, css3 ------- day68
When I first thought about this small application, I took it for granted that it could be the same as a clock, as long as I get the rotation angle. Of course, I actually do the same, but there are some places in the middle that I did not think of, and then I learned a lot...
First, let's consider what we need to do if we want to achieve a pair of eyes that can follow the mouse

The width of a convex polygon is defined as the minimum distance between the parallel tangent. This definition has been reflected in the word width. Although the tangent of a convex polygon has different directions, and the width of each direction (usually) is different. Fortunately, not all directions must be detected.
Assume that a line segment [A, B], And twoAAndB. By rotating the lines around these two points, the distance between them increas

Rotate a one-dimensional array of n elements to the right by k steps.For instance, with n=7 and k=3, the array {a, b, c, d, e, f, g} is rotated to {e, f, g, a, b, c, d}.
In my previous post we discussed about finding an element in a rotated array. You might ask, how do we rotate an array?
The straight forward way is to allocate a temporary array of size n, and then copy elements starting from index k to the new array, and copy it back to the old array. This is h

Rotate string left (string)Question:Define the left rotation operation of the string: Move several characters before the string to the end of the string.For example, the string abcdef is rotated two places to the left to obtain the string cdefab. Please implement the left rotation function of the string.Requires that the complexity of the string operation with a length of N is O (n), and the auxiliary memory is O (1 ).
Ideas:
If the string is abcdefg, it must be left-handed. $ indicates the
