Tricks used to reduce time complexity

WebFeb 13, 2024 · Reducing the runtime by a factor ten may be extremely valuable, but doesn't reduce time complexity. It is in practice more valuable than reducing time complexity by a factor log log n. Next thing to remember: In many cases "could you make it faster" has the valid response "Probably, but I wouldn't bother". Making it faster takes time in money. WebMar 5, 2024 · So here is an algorithm which computes the same result in O (n) time: sum_A ← 0 for i ← 0 to n-1 sum_A ← sum_A + ArrayA [i] sum_B ← 0 for j ← 0 to n-1 sum_B ← …
