+'''Given n balloons, indexed from 0 to n-1. Each balloon is painted with a number on it represented by array nums. You are asked to burst all the balloons. If the you burst balloon i you will get nums[left] * nums[i] * nums[right] coins. Here left and right are adjacent indices of i. After the burst, the left and right then becomes adjacent.
+
+Find the maximum coins you can collect by bursting the balloons wisely.
+
+Note:
+(1) You may imagine nums[-1] = nums[n] = 1. They are not real therefore you can not burst them.
+(2) 0 ≤ n ≤ 500, 0 ≤ nums[i] ≤ 100
