Thanks man. This question is quiet similar to yesterdays one based on 0/1 knapsack pattern. That actually helped me solved this one on my own with little help from your explanation.

That is really good explanation..I think it is a very good approach for recursion/dp problems ...most of difficult things are sorted once we draw the rec tree

I tried the n-ary recursion tree + memoization along with freq compression but that also TLE'd at 85/90 test cases. Any idea why is that different than the binary recursion based solution?

can anyone explain me in code where we check that the target[tpos] and the words[0 to wordsize-1] is equal or not.
for myself it is check all and include all and exclude all . if you have beter understanding . explain to me .
