minus-squareVenator@lemmy.nzlinkfedilinkarrow-up0·3 months agoWhy would you want a specific time complexity? Wouldn’t it be better if it’s faster?
minus-squareJaddedFauceet@lemmy.worldlinkfedilinkarrow-up0·3 months agoLikely they want a lower time complexity. for example a question can be trivially solved in O(n^2). but there is no know < O(n) solution, so they ask for O(n)
minus-squareTiefling IRL@lemmy.blahaj.zonelinkfedilinkarrow-up0·edit-23 months agoMost of the time O(n^2) is optimized to O(n log n). You’ll get some sort of award if you can figure out a sorting function that runs in O(n).
