lli i,a, b = sum[endi]-sum[start-1],c=INT_MAX;ccan be larger thanINT_MAXIf you want to learn the concept behind this problem then go through Matrix chain multiplication DP, it is a very famous DP problem and has clear explanations(you can check Cormen or any online articles). This N-slimes problem is very similar to that but instead of multiplication, we do addition.
