 Given two arrays one with expected numbers and other with actual numbers determine which number is missing in the actual array2 AnswersXOR all the elements together - the result will be the missing number. This works assuming there's only one missing number, but it's the fastest way. If there are multiple missing elements, use a hashtable.missing = SUM(expected) - SUM(actual) (again works only if 1 no. is missing!)

The number of simulations can be lowered using variance reduction techniques such as antithetic, control variante, etc.

 Problem: Array of 100 integers between 0 and 100. One integer is doubled, find out which. Question: Which methods exist and how do they compare?2 AnswersThe worst answer in this case is an algorithm, the interviewer clearly did not ask for that. An important question to ask is whether they want the Position of the doubled integer or only its value. Possible solutions: sort (quick sort, radix-sort/K-sort), search, counting, Polynom, a[0]+a[1]+...a[101] - 0+1+2+99+100 = doubled integer.sum on N numbers in (N*N+1)/2. Add all the numbers and find out how much it differs from this sum
