Allo Well the problem is actually extremely simple, which is makes me frustrated cause i can't seem to get my head around it. Well here it is: I get the user to fill up 2 arrays with integer numbers Then i have to make a union of those arrays and put them into a 3rd array ex: 1st Array: 2,3,2 2nd Array: 4,5,2 But repeated numbers arent added into the third array, hence in this case the 3rd Array would be: 3rd Array: 2,3,4,5 Thanks in advanced xD |

Hmmm.... go through the first array first, record down ith number (in the 3rd array), and number recorded shows up again, dont count it (so you probably need a nested loop) and do the same for the 2nd array, using 3rd array to check and then just simply sort the 3rd array  no? |

Let's think about some base cases. Union of two empty arrays? Union of one non-empty array and an empty array? |

Union of two empty arrays? Union of one non-empty array and an empty array? that doesnt matter much does it? if its empty, then length of array is 0, which means the "searching" loop wont even run?  |

I am trying to get the OP to think algorithmically; to think before writing code. But to put that into code:
