Write a function that takes a string and an integer $(n)$ as input. The program will convert the final $n$ characters to uppercase. For example 'BallOfStrinG' with

$n=6$ should return 'BallOfSTRING'.

In $[5]$: $M$ def string$\_$convert$($string$,$ n$)$:

In $[6]$: $M$ assert string$\_$convert$(\text{'}$BallofStrinG$\text{'},6)==$ 'BallOfSTRING'

assert string$\_$convert$(\text{'}$Ilovemaps$\text{'},4)==$ 'IloveMAPS'
