;Example test cases; *   1 -> 1 1 *   2 -> 1 18 *   29 -> 4 11 *   42 -> 5 6 *   57 -> 8 4 *   58 -> 8 5 *   72 -> 6 4 *   89 -> 9 4 ;Details; The representation of the periodic table may be represented in various way. The one presented in this challenge does have the following property : Lantanides and Aktinoides are all in a dedicated row, hence there is no element that is placed at 6, 3 nor 7, 3. You may take a look at the atomic number repartitions [https://en.wikipedia.org/wiki/Periodic_table#/media/File:Simple_Periodic_Table_Chart-blocks.svg here]. The atomic number is at least 1, at most 118. ;See also: *   [https://en.wikipedia.org/wiki/Periodic_table the periodic table] *   [https://twitter.com/CompSciFact/status/1537447575573233666 This task was an idea from CompSciFact] *   [https://ascii.periodni.com/index.html The periodic table in ascii] that was used as template
