The Gravity Equation

Function Name: gravityEquation$()$

Parameters: calculations $($ str $)$

Returns: correctResults $($ list$)$

Description: As a new NASA hire, you have been tasked with helping Murph, a brilliant NASA sci$-$

entist, solve the gravity equation.

You are given a parameter, calculations $($ str $),$ which contains multiple "calculations" separated by

underscores $1.$ Each calculation is mix of digits and letters. Write a function that analyzes each

calculation by counting how many digits and letters it contains. If the number of digits and letters in

the calculation are equal, then that calculation is considered valid. For each valid calculation, ex$-$

tract and store only its digits. Return a sorted list of these integers in ascending order.
