+ since list1 and list2 are equalised,any change in the one of the list makes
+automatically change in the other list.
+ therefore,list2[0]="1 will also change the value in list1 also
+ list1=list1+[] and list1+=[] are different
+ because, by using list1+[] will not change the values in the list2 of same
+indev,whreas by using list1+=[] will change the values of both lists,if one is
+changed
