    Following are the program in python language

    def cat_rev (x, y, z) : # function definition

    x=x[::-1]# reverse the first string

    y=y[::-1]# reverse the second string

    z=z[::-1]# reverse the third string

    z=x+y+z; #concat the string

    return (z) #return the string

    #main method

    s=input ("Enter the first string:") #read the first string

    r=input ("Enter the second string:") #Read the second string

    t=input ("Enter the third string:") #Read the third string by user

    rev1 = cat_rev (s, r, t) #function calling

    print (rev1) # display reverse string

    Output:

    Enter the first string:san

    Enter the second string:ran

    Enter the third string:tan

    nasnarnat

    Explanation:

    Following are the description of program

    In the main function we read the three value by the user in the "s", "r" and "t" variable respectively. After that call the function cat_rev () by pass the variable s, r and t variable in that function. Control moves to the function definition of the cat_rev () function. In this function we reverse the string one by one and concat the string by using + operator. Finally in the main function we print the reverse of the concat string.
