1.	What do you understand by mutability? What does "in place" memory updation mean?
Answer» Mutability means to modify in place where \'in place\' means the modification is done at the original memory address and no other memory location is referred(as in the case of strings if we give new value to a existing variable, it refers to a new memory location)
