    '''
    This function returns True if the given string is
    a Palindrome

        string (str)
    returns:
        flag (bool)

    '''
    This function returns the magnitude of the square root of the number

    This function returns first maximum and the second maximum

    This function sorts the array giving higher preference to even numbers

        sort_arr = [2, 6, 88 ,7 ,15]

def eqn_solver(A, B, C):
    '''
    This function solves a two variable system
    i.e.,
        A = [ 1, 2 ]
        B = [ 3, 4 ]
        C = [ 5, 6 ]
        then it means
        1x + 3y = 5
        2x + 4y = 6
        Hence you are required to find x, y for such a linear system
    args:
        A, B, C (list, list, list) representing coefficients in the equation
    returns:
