******output*******
enter the number153
The no.is armstrong    

Algorithm:
1. Start
2. Read A
3. Set temp=A
4. Check while (A)
    if true:
    a)Set D=A%10
    b)Set sum=sum + (D*D*D)
    c)Set A=A/10
    [end of while structure]
5. Check if sum = temp
    a) Write: The no. is amstrong
6. else
    a) Write: The no. not is amstrong 
    [end of if else structure]  
7. Stop
