Tony's Log HackerRank - Knapsack 30123 456789 16 18192021222324 293031 Very good problem to learn knapsack (complete knapsack in this case). My brutal-force solution in Python got AC too, which surprised me a bit. Here is the ideal DP solution. Just check comments:...
vector<LL>in(n); REP(i,0, n) cin >>in[i]; cout<< calc(in) <<endl; }return0; } But all TLE.. so there are must be a O(n) solution, and there is..what is better than a standard DP in cerntain cases? Greedy.
