[Algorithm Notes] C(n,m) does not cross the boundary but A(n,m) crosses the boundary; C(n,1)+C(n,3)+C(n,5)… and other binomial theorems; ‘memset’: identifier not found
https://codeforces.com/contest/893/problem/E Solution where C(n,m) does not cross the boundary but A(n,m) crosses the boundary C(n,m) = A(n,m) / (n-m)! This question requires modulo 1e9 + 7, but only addition, subtraction, and multiplication can modulate it, but division cannot. Therefore, this A(n,m) needs to store the original value. The original value is too large and becomes […]
Flutter Performance Revealed: RepaintBoundary
Author: xuyisheng Flutter draws Widgets on the screen. If the content of a Widget needs to be updated, it can only be redrawn. However, Flutter will also redraw some Widgets, and the contents of these Widgets are still partially unchanged. This can impact the performance of your application, sometimes dramatically. If you are looking for […]
