Integer array firstValues contains the first NUM$\_$VALS elements read from input, while integer array secondValues contains the next NUM$\_$VALS elements read from input. If an element in firstValues is less than or equal to the corresponding element in secondValues$,$ then replace the element in firstValues with $-1.$ Otherwise, add $4$ to the element in firstValues.

Ex: If the input is:

$453915471450251648473036$

then the output is:

$4943-1-1-154$
