Open Word, the window default ruler is 2, 4, 6 ... 38, what unit is this number? Is it centimeter? It is not; it is in the character, in the format of the fifth words in the song, each row can enter 38 Chinese characters. However, this setting is inconvenient to use, especially in tabulation, drawing, it is not intuitive, it is necessary to modify the ruler in centimeters. From the Tools menu, open the Opt

How do you make a ruler that is the same as the actual size in PS? Final effect: 1, the fill background is gray, then fill the pattern 2, create a new layer, use the gradient, change the layer mode to soft light, as shown; 3, new layer, create rectangle, add layer style, such as figure; 4, and then create the blue rectangle as shown in the figure, add layer style, such as figure; 5, dra

After years, to now also did not seriously write code, just the company has the demand, spent an afternoon, wrote a ruler effect of the custom view, the effect is OK, but there are a lot of places to improve, I hope you correct!!!

Title Link: http://www.51nod.com/onlineJudge/questionCode.html#!problemId=1127Idea: The ruler method, at first I consider updating the right pointer until I encounter the same character as the pointer pointing to the L, and found that this does not AC. So a change of thinking.Always update the r pointer until all characters have appeared again, update the answer and left pointer, resulting in a notch, and then update the R pointer.1 /*2 ━━━━━┒ギリギリ
