NASA has intercepted a mysterious signal from Mars filled with random letters and numbers. Scientists believe each number in the message represents an energy pulse needed to activate an ancient Martian device.
Your task is to decode the message by identifying all the complete numbers hidden within the string and finding their total sum. Ignore all non-digit characters, but remember that numbers may have multiple digits.
For example, the signal 'a9x12b3' should return 24, since the hidden energy pulses are 9, 12, and 3. Can you unlock Mars’s secret code?
