WebDec 18, 2024 · Algorithm Efficiency. The efficiency of an algorithm is mainly defined by two factors i.e. space and time. A good algorithm is one that is taking less time and less space, but this is not possible all the time. There is a trade-off between time and space. If you want to reduce the time, then space might increase. WebThe time complexity, measured in the number of comparisons, then becomes T ( n ) = n - 1.
