Matrix-Patter-Fill-2

Recursive function which goes through an empty matrix passed to it which has many levels of inner matrices with varying depths, all of them being empty.

Input (global values): strVal = “abcdefghijk”, PAT_LEN = someInt (some +ve int) • The program needs to fill in the pattern as per the values in the above identifiers. • The rules to be followed are the following:

1. Assuming the above value is in strVal, after ‘k’ is filled into an empty list, it should wrap around from ‘a’. Note: The string used, needs to be configurable manually.
2. You can assume that the list object passed to the function has sub-lists, which are all empty.
3. Returns the same list object back which is filled in with the pattern as per configuration values.
