Consider the following data field and method. Method maxHelper is intended to return the largest value among the first numVals values in an array; however, maxHelper does not work as intended.

private int$[]$ nums;

$//$ precondition: $0<$ numVals $<=$ nums.length

private int maxHelper$($int numVals$)$

$\{$

Line $1$: int max $=$ maxHelper$($numVals $-1)$;

Line $2$: if $($max $>$ nums$[$numVals $-1])$

return max;

else

return nums$[$numVals $-1]$;

$\}$

Which of the following corrects the method maxHelper so that it works as intended?

Responses

Insert the following statement before Line $1.$

if $($numVals $==0)$

return numVals;

Insert the following statement before Line $1.$

if $($numVals $==1$

return nums$[0]$;

if $($numVals $==0)$

return numVals;
