I want to try to understand recursive functions in J. To start this learning process, I want to investigate J verbs that will generate a doubling sequence. For example, the verb 'd' where x = the starting integer, and y = the number of iterations:
2 d 6 2 4 8 16 32 64 5 d 4 5 10 20 40 7 d 10 7 14 28 56 112 224 448 896 1792 3584 Define three different simple recursive verbs in J, to implement this recursive doubling function: 1. d1 - Just calling the function recursively 2. d2 - Using the Power operator ^: 3. d3 - Using Spread S: and Memo M.
