### Software Engineer Intern at Motorola Mobility was asked...

Mar 19, 2009
 Write a function in Java that will take a sorted array of ints, possibly with duplicates, and compact the array removing all the duplicate numbers. That is, if the contains the numbers - 1, 3, 7, 7, 8, 9, 9, 9, 10, then when the function returns, the contents should be - 1, 3, 7, 8, 9, 10. Be sure your answer is as efficient as possible. Describe the efficiency of your algorithm using big O notation.5 Answerscreate temp array; starting from the second element copy the i'th char if input[i-1] != input[i] return tempoh efficiency is O(n)you can't create a temp array because you don't know the size until after you process. you could count the number of dupes in one pass, then allocate the array, then do the compacting. or you could allocate the array equal to the size of the original and accept that some elements will be null (or -1, or whatever). or you could use some dynamic data structure like an ArrayList to build the compacted list and convert it to an array at the end (ArrayList.toArray(...)). regardless, it's still O(n) and uses 2x the memory. makes me think there's a more elegant solution though.Show More Responsesdo bitwise XOR of consecutive numbers. When the xor is 0, you know the number is duplicate. It will require single pass thru the array to identify number of duplicates in the array.you can also use 2 index, at the beginning they both = 0, then you will have a previous and a next, if previous value = next value increment next index until next value != previous value then increment previous index by 1 and assign "next value" to it and so forth until you "next index reach the end of the array and then increment all previous index assigning null or -1. O(n) without using 2x memory. Anyway, I hope it is not too confusing, its late but I hope you got the big picture.

 Do you know how to write your name?3 AnswersI don't care who you are, That's so funny and accurate!Thanks :). Happy Holidays.If Motorola, Pace, and cisco and most of all Comcast even knew 1 tenth of how CTDI is screwing and lying to all of them, CTDI would be out of business in a day. Someone with more balls than me should report them.

Jul 17, 2012
 Name a time when you had to overcome objectives to get the sale3 AnswersBeing in sales you always have to overcome objectiveHow is the job going now? Is it worth the \$8 salary? How are the comissions working out? I have a interview next week.I no longer work at Comcast, however it was a cool place to work at many of the employees in the tele-marketing department are students. So the part time aspect of the department fit their schedules. If you are a decent sales rep you can easily meet your quota. and reaching your quota you will do good. Good luck Oh yeah they offer free cable and internet but I think its \$5-\$10 per month for the Phone.
