Here's my try at this.
A=:'73167176531330624919225119674426574742355349194934'
B=:'96983520312774506326239578318016984801869478851843'
C=:'85861560789112949495459501

Same happens for problem nr 4, that of the maximum palindrome with
five or six figures recently discussed.
timespacex ' >./ ([: */ "."0)"1 (#~ ( 13 = ''0'' i.~ ])"1) 13,\ n'
