Just KNIME It! Round 3

You are using KNIME to monitor the daily price of a product online. After using the Line Plot node to visualize the daily prices you have already gathered, you notice that they are often constant for a certain number of days before changing again. You want to create a new column in the price data you have at hand, named "Change", such that its value is 1 if a daily price changed with respect to the previous day, or 0 if it remained unchanged. For the first daily price in the data, the "Change" value should be 1.
