Least common element in given two Arithmetic sequences | Function to find the smallest element common in both the subsequences.
If a is equal to c.
If a exceeds c.
Check for the satisfying equation.
Least value of possible_y satisfying the given equation will yield True in the below if and break the loop.
If the value of possible_y satisfying the given equation lies in range [ 0 , b ].
If no value of possible_y satisfies the given equation.
