Complete main$()$ to read dates from input, one date per line. Each date's format must be as follows: March $1,1990.$ Any date not following

that format is incorrect and should be ignored. Use the substring$()$ method to parse the string and extract the date. The input ends with $-1$

on a line alone. Output each correct date as: $3-1-1990.$

Ex: If the input is:

then the output is:

$3-1-1990$

$12-13-2003$

Use the provided getMonthAsInt$()$ method to convert a month string to an integer. If the month string is valid, an integer in the range $1$ to $12$

inclusive is returned, otherwise $0$ is returned. Ex: getMonthAs Int $("$February$")$ returns $2$ and getMonthAs Int $("7/15/20")$ returns
