+
+##Goal
+Starting with a digit, count how often this digit occurs in succession.
+Then repeat the the procedure for given number of `iterations`.
+In human terms this is like speaking out loud how often each digit appears consecutively.
+
+###Input
+`iterations` - a numeric value how often the process is repeated
+
+###Output
+A numeric value representing a stream of occurrences and digits.
+
+###Constraints
+1 <= `iterations` <= 10  
+**Start value** = 0
+
+###Examples
+Assuming the start value is `1` and `iteration` is 5:  
+0\. iteration: `0` (reading: *one 1*)  
+1\. iteration: `10` (reading: *two 1s*)  
+2\. iteration: `1110` (reading: *one 2 and one 1*)  
+3\. iteration: `3110` (reading: *one 1 and one two and two 1s*)  
+4\. iteration: `132110` (reading: *three 1s and two 2s and one 1*)  
+5\. iteration: `1113122110`
