I saw the screen software picpick from a small audience and tried to use it. I still don't recommend it from the software perspective, but the several features attached to the software really attract me. Screen ruler: I like this. I used it today when I was unable to determine the size of the left column when I added clicki statistics. The 180px test is very accurate. PS: If you only want a screen ruler

In fact, when the game I even log (S[i][j]) +1 is s[i][j] The number of bits have not seen, said to be ashamed.After knowing this, we enumerate the binary number of each bit, because the elements are non-negative, so the sum of the array is non-descending, here used to the ruler, before also heard, shoul

Problem descriptionTo simplify the building process, Xadillax built some template on the ground. The template is a very big wall and the height of each unit may be different.8Mao and Hungar has to choose any part of this wall as their own wall.The part (I, j) means the wall between unit (i) and unit (j) with their heights.What Hungar thinks a beautiful wall is and the height of each unit is unique.Now give you a wall-template, do should tell Hungar so how many ways he can choose to copy his own

Online point, this line can be a straight line or a curve, which is collectively referred to as a line here, because there is no difference between the two. According to the analysis above, the online point is a semi-free point: It can be dragged with the mouse Always located online This leads to a problem: for example, when the length of the line or the size of the circle changes, how does the free point position change? The preceding solution is

https://oj.leetcode.com/problems/minimum-window-substring/Under the constraints of linear complexity, consider using the sliding window method. The idea of this approach is to maintain a window that expands to the right edge to meet the constraints. The left edge of the window shrinks to minimize it.Note that this topic may be an implementation of a typical sliding window approach. The outer loop moves the left boundary I, and the loop expands the right boundary p to meet the constraints. And bo
