@ is a part of the array or the rest of the array

If there is 2 entries:

B(a) = a

B(a,b) = a^b

Otherwise, start the process below:

• Scan the array:

• If you find an entry that is 1, then:

  • If it is the last entry, remove it from the array (Example: B(5,3,1) = B(5,3)) else:

  • Keep advancing through the array until there is a non-one entry, then turn the 1 entry into the non-one entry and reduce the non-one entry by 1

  • If there is no non-one entries, then the result is 1

• Otherwise, B(a,b,c@) = B(a,b-1@,B(a,b,c-1@))
