Here's a question that I sometimes ask an engineering candidate:
You have a list of 100 numbers with values in the sequence 1 to 100. Each number of the sequence appears once except that one value is missing and one value is repeated. Determine which value is missing and which one is repeated.
Notice that I didn't say anything about writing code.
If asked,I will answer no questions like "are they in order?" and so forth.
