Answer 1

Other posters have given you 2 solutions ... I think understanding why it happens is good too :)

Let's take your example 1, 2, 2, 3, 5 and follow the code line by line

i = 0;             /* first time through the loop; i "points" to 1 */
if (a[i] == 2) ... /* nope; next loop */
i = 1;
if (a[1] == 2) ... /* yes! let's go inside the if */
                   /* move all elements back
                   ** and "decrease" array length */
                   /* array is now 1, 2, 3, 5 */
                   /* next loop */
i = 2;
if (a[i] == 2) ... /* nope; OH! Wait ...
                   ** a[1] is the new 2 and it wasn't checked */
