Question

To delete an element in the list at the end, we can delete it without any difficult. But, assume if we desire to delete the element at the straining or middle of the list, then, we ought to rewrite all the elements after the position where the element that ought to be deleted exists. We ought to shift (r+1)^th element to r^thposition , where 'r' refer for position of deleted element in the list, the (r + 2)^th element to (r + 1)^th position,  and it will continue till the (n)^th element to ( n-1 )^th position, where n refer to the number of elements in the list, and after that the count is decremented.

From the above instance, if we desire to delete an element '44' from the list. We ought to shift 55 to the 4^th position, 66 to the 5^th position, and 77 to the 6^th position.
