Subset-sum problemWe propose an efficient, sub-optimal prefix code construction method for discrete sources with a finite alphabet and known probability mass function (pmf). It is well known that for a source that puts out symbols x i with probability p i , the optimal codeword lengths are ...
Solution 1. Enumerate all possible subsets and check if their sum is the target The runtime of this solution is O(2^n). This enumeration algorithm is similar with the problemSubsets. The difference is that Subsets has to get all possible subsets. But this problem can terminate the check ea...
