License plates in India begin with a code that identifies the state and district where the vehicle is registered, and this code is followed by a four$-$digit identification number. These identification numbers are given sequentially, starting with $0000,0001,0002,$ etc. Once this sequence reaches $9999,$ a letter from the set $\{$A$,...,$ Z$\}$ is added $($in order$),$ and once these run out, additional letters are added, and so on$.$ So the sequence of identification numbers proceeds as follows: $0000,0001,...,9999,$ A$0000,$ A$0001,...,$ A$9999,$ B$0000,$ B$0001,...,$ B$9999,...,$ Z$0000,$ Z$0001,...,$ Z$9999,$ AA$0000,$ AA$0001,$
