+## Solution in CESIL
+
+OK - last weeks CESIL challenge was easier than this weeks....
+
+**CAVEAT:**
+ * Can't cope with "odd minutes" as this will lead to a fractional angle {and CESIL is integer only}
+ * Can't handle non-integer input - so the times have to be put in without the : so `03:30` is put in as `0330`
+```
+( Compute the angle between the hour and minute hand
+( Input contains of triple hour/minute & answer so
+( can check calculations are OK!
