Given the following code segment, what is printed? int 1 x =(2, 4,6,8,10}; System.out..println (x[2]++) ; 6 2 7 3 If the following operations on the stack is performed and stack size is 5; push (1) ;pop () ; push (2) ;push(3) ; pop () ; push (4); pop () ; pop (); push (5) ; After the last operation, the total number of elements present in the stack is 2 3 1 4 In insertion sort algorithm............ the minimum key is repeatedly identified. a number of items must be shifted to insert each item in its correctly sorted position . the largest key is accumulated on the low indices. the sorted items are accumulated on the right . Which of the following is the disadvantage of the array? Waste of memory if the elements inserted are less than the allocated size . Elements can be accessed sequentially. Index of the first element in an array starts with 0 . Stack and Queue data structures can be implemented through an array.
