Duplicate Elements of An Array. One common misunderstanding is that coding interview is all about solving algorithm questions.

Duplicate Elements of An Array

In fact, the answer itself is only part of the evaluation and sometimes it is not the most important part at all. There are many other factors being evaluated during an interview. For instance, your analysis process is at least equally important. More specifically, interviewers care a lot about how you approach a problem step by step, how you optimize your solution, how you compare different approaches and so on so forth. So in this post, we want to focus more on discussion and analysis. Question Given an array of string, find duplicate elements. For instance, in array [“abc”, “dd”, “cc”, “abc”, “123”], the duplicate element is “abc”. Solution. at master · epibook/ Solutions - Elements of Programming Interviews.

}} Immutable objects have many advantages, including: Safe for use by untrusted libraries. Thread-safe: can be used by many threads with no risk of race conditions. Making immutable copies of objects is a good defensive programming technique. The JDK provides Collections.unmodifiableXXX methods, but in our opinion, these can be unwieldy and verbose; unpleasant to use everywhere you want to make defensive copies unsafe: the returned collections are only truly immutable if nobody holds a reference to the original collection inefficient: the data structures still have all the overhead of mutable collections, including concurrent modification checks, extra space in hash tables, etc.

An ImmutableXXX collection can be created in several ways: Versus. - Problem PALIN. The Billion Dollar Startup Club. Top 10 Algorithms for Coding Interview. PDF: Update History, Latest version (8/1/2016) The following are the common subjects in coding interviews.

Five-essential-phone-screen-questions - steveyegge2. I've been on a lot of SDE interview loops lately where the candidate failed miserably: not-inclined votes all around, even from the phone screeners who brought the person in initially.

It's usually pretty obvious when the candidate should have been eliminated during the phone screens. Well, it's obvious in retrospect, anyway: during the interviews, we find some horrible flaw in the candidate which, had anyone thought to ask about it during the phone screen, would surely have disqualified the person. But we didn't ask. So the candidate came in for interviews and wound up wasting everyone's time. Antipatterns I've done informal postmortems on at least a hundred phone screens, many of them my own. The first pattern is that for most failed phone screens, the candidate did most of the talking. That's how many/most phone screens go wrong. The right way to do a phone screen is to do most of the talking, or at least the driving. Let's assume that there's an a. A computer science portal for geeks. Online text editor - collabedit.
