So the algorithm is actually adding up all the spreads greater than 0 can

/** 188. best time to Buy and Sell Stock IV * 2016-6-6 by Mingyang * This topic my approach is to set up a number of transaction for the two-dimensional dp,t[i][j]i, J is the days * Also is to complete the maximum value of the I transaction within J days * T[i][j]=max 1. T[I][J-1]------> J Day does not trade at all * 2. (Prices[j]-prices[m]) +t[i-1][m]------all the maximum * for m=0,... j-1---that is, in M days to complete i-1 transactions, the last t

Say you has an array for which the i-th element is the price of a given-stock on day I.If you were-permitted-to-complete at most one transaction (ie, buy one and sell one share of the stock), design an AL Gorithm to find the maximum profit.Invariant is that if day I and J days are the highest-yielding buy and sell points respectively, then prices[i] must be the lowest price in the range [0, J].Use traversal
