Integer numElems is read from input and integer array patientNumbers is declared with size numElems. Then, numElems integers are read from input and stored in patientNumbers. For each element in patientNumbers that is equal to $1,$ increment count.

Ex: If the input is

$5$

$9,6,1,1,-9$

then the output is:

Total: $2$
