We were reviewing the whitepaper - the chutes and ladders of customer identity from Gigya which is a leader in Customer Identity and Access Management Industry. The title uses an analogy of a well-known game. This is a whitepaper that introduces the delights and the pitfalls in customer experience with identity. CIAM solutions make it easy for a customer to be recognized, remembered, informed and subscribed for recommendations which become more and more personalized with every interaction until she becomes a champion for the brand in her social circle.
Today we start reading another whitepaper which informs us how CIAM solution can make sure that the corporate strategy is not hostage to the IT strategy. This draws observations from the Forrester 2017 report based predictions on dynamics that will shape the future in the age of customer. That report mentions "how competitive markets are on the move. Banks try to innovate so that they are displaced by digital banks, retailers confront the digital threat with store closing and enhanced omni-channel and mobile efforts. Manufacturers are taking to an online presence. Relationship driven investment firms battle software companies takeover and even commodity and utility companies are launching customer initiatives." Behind all these moves, the customer is the one driving these.  They are demonstrating a willingness to shift spend. They are rewarding or punishing companies based on a single experience. One poor experience triggers an immediate and prolonged shift in spend to competitor. Companies are worrying about losing upto half their revenue. Even companies that bind customers to contracts feel the heat. Revenue risk is not the only symptom. Customers and businesses have started using the language of emotions. It's no longer merely the appeal and use of brands where emotions are put to work.Companies are recognizing that customers don't forgive.  Moreover these numbers are not even measured and reported. This report mentions that companies can classify operations into emotions matrix and focus on repairing those that provoke negative emotions. In fact this report clearly indicates that there will be some in-roads made in this direction this year.The third and perhaps relevant observation for CIAM solutions in this report is that the human beings are in a constant mode of multitasking and handling distractions. This is about customer journey mapping which is important for understanding and anticipating customer needs as they move across touchpoints. Here customer experience professionals  are going with micro strategies. For example they are determining signature moments where customers appreciate the value the most. Another example is their search for ways to come through with the brand so that a single moment can be stretched over time. This microdesign is more effective and pertinent to the customer rather than larger sweeping initiatives.

Find the lowest common ancestor between two nodes.
Here the strategy is very simple. The lowest common ancestor is one that has the nodes in both the sub-trees. As we recursively search the tree if the root has a node in the left  and the node in the right, then it is the lowest common ancestor. If only the left is available, we return left. If only the right is remaining we return right. Finally if neither is present, we return null. The edge cases are that the root itself is one of the nodes required or the root is null.
This method assumes both nodes can be found in the sub-trees
