can anyone help me with comparing numbers in array? Please let me know the instruction how to do it, pseudocode shoule be fine. Thank you
For example,

user enter: 1 2 1 1 2, 3, etc;
output: Duplicate number are: 1 1 1, 2 2

Use two nested loops. First loops thru your numbers. The second (inside the first) again loops thru the numbers comparing the number pointed to by each loop. There's a little more bookkeeping that needs to be done to make sure you don't count the numbers more than one. I leave that for you to ponder.
