If your solution is asymptotically faster than the one in the main branch. Otherwise, if I try to "go back one step" on the FIRST element that I initially modified, it means that there were no solutions. If you were only permitted to complete at most one transaction (ie, buy one and sell one share of the stock), design an algorithm to find the maximum profit. IT IS READ ONLY, InterviewBit – Best Time to Buy and Sell Stocks I. And the other is also checking from begins to ends, but 'ends' is getting smaller(-1).
