You are going to build a stone wall. The wall should be straight and N meters long, and its thickness should be constant; however, it should have different heights in different places. The height of the wall is specified by an array H of N positive integers. H[I] is the height of the wall from I to I+1 meters to the right of its left end. In particular, H[0] is the height of the wall’s left end and H[N−1] is the height of the wall’s right end.
As many small and big companies, organizations try to develop their own blockchain technologies IBM has developed its own. It is called Hyperledger, which originally was the closed source code project. But somehow IBM decided to make it open source and share its vision regarding to blockchain technolgies.
