0 I know that in linux, opengl can work with video memory directly. Is this true for windows? I'm not talking about the interaction of opengl and window manager. I am talking about drawing primitives, images, etc. That is, the question is whether opengl uses the winapi functions for drawing shapes, or it implement thats functions, working directly with memory. if it can bypass winapi, then how can i write similar native code to draw pixels in a windows window? (Without winapi or external shells) opengl graphics share | improve this question edited Nov 12 '18 at 3:38 Nicol Bolas 287k 33 478 649 asked Nov 12 '18 at 0:24 Daniel Holmes Daniel Holmes 1 2 closed as unclear what you're asking by Nicol Bolas, Rabbid76, lagom, V-rund Puro-hit, Foo Nov 12 '18 at 7:17 Please clarify your specific problem or add additional details to highlight exactly what you need.

XOR greater than 4 of even-even or odd odd pair Given an array of even and odd numbers, I want to get the number of (even-even) and (odd-odd) pairs whose XOR is greater than or equal to 4. I tried this with the code below but it runs in O(n^2), (yikes). Please can anyone suggest a means of optimization? n = int(raw_input()) #array size ar = map(int, raw_input().split()) #the array cnt = 0 for i in xrange(len(ar)): for j in xrange(i+1, len(ar)): if ar[i] ^ ar[j] >= 4 and (not ar[i] & 1 and not ar[j] & 1): cnt += 1; #print ar[i],ar[j],ar[i]^ar[j]; elif ar[i] ^ ar[j] >= 4 and (ar[i] & 1 and ar[j] & 1): cnt += 1 print cnt EDIT: I discovered something. any number x, which gives a remainder after % 4, i.e x % 4 != 0, will result to 2 when XORed to a number -2 itself. For example, 6. It is not divisible by 4, therefore, 6 XOR 6-2 (4),==> 2. 10 is not divisible by 4, hence, 10 XOR 10-2 (8) ==> 2. Can you please tell me how this could help me optimize my code?
