The O(1) solution is limited by the address space of the registers in the CPU and ALU. So for very large powers of two, like above 2^64 it may not be as efficient. Depends on how many bits the registers can store. Disclaimer: This is just thought aloud. Might need more verification.

How they can start to do coding and after doing bca they should do masters for multinational companies . And for multinational companies only coding is important or any more thing we have to study. Because we are learning basic things of coding . And one more thing i am noob in coding so how can i start coding can you explain in video or reply here . And for coding you can prefer any book .

@TheMorhaGroup Жыл бұрын

I suggest sticking to your passion, if you love technology then pursue that, allow everything else to follow suit. I shall give you an example, a strategy game like Yu-Gi-Oh requires a lot of reading, however reading is not a necessity, if one has a passion in Yu-Gi-Oh, they simply need to play the game, memorising the cards they need to know, eventually memorising what words relate to what meaning, after decades of playing Yu-Gi-Oh, do you not think he would have grasped basic reading, enough to play Yu-Gi-Oh effectively? Analogous to you grasping maths, enough to be effective in the path of tech
