The space - time trade off, Data Structure & Algorithms

Assignment Help:

The best algorithm to solve a given problem is one that requires less space in

memory and takes less time to complete its execution. But in practice it is not always possible to achieve both of these objectives. There may be more than one approach to solve a problem. One approach may require more space but less time to complete its execution. The 2nd approach may require less space but takes more time to complete execution. We choose 1st approach if time is a constraint and 2nd approach if space is a constraint. Thus we may have to sacrifice one at cost of the other.  That  is  what  we  can  say that  there  exists  a  time  space  trade  among algorithm.
