I have made a video tutorial on how we can compare substrings in constant time using string hashing in C++. I have taken the problem from Codechef May CookOff "Chef Chefina and their friendship" which can be solved using hashing. Check it outhere Thank You!
String Hashing Hashing algorithms are helpful in solving a lot of problems. We want to solve the problem of comparing strings efficiently. The brute force way of doing so is just to compare the letters of both strings, which has a time complexity of O(min(n1,n2))<math xmlns="http...

It also implements block encryption algorithms, stream cipher algorithms, hashing algorithms, public key algorithms (i.MX6UL/i.MX7D/S), and a hardware random number generator. The official Yocto release (L4.1.15_2.0.0-ga) of the i.MX only enable cryptodev for accelerating symmetric alg...
(for costs , space and any other reason). So the Idea is o make a new document to do the same on the new Yocto enviroment. Infact the step and the stuff to change are ecxatly the same, but they are to be done in different way. When you want to make your custom board what ...

the mxc_v4l2_tvin test application can use overlay framebuffer as V4l2 capture buffer directly. 0004-Max9286-skip-AP0101-camera-re-initialization.patch If the camera board's power had been kept after initialized, this patch will bypass the re-initialization to reduce the start up time....
