Problem of the day
Tip 1 : During an interview, never say that you don't know the answer, keep trying and the interviewer will help you himself.
Tip 2 : Keep speaking up the approach going on in your mind, they want to judge your approaches much more than whether the answer is right or wrong.
Tip 3 : Be confident, cheerful, keep smiling, and continue making eye contact with the interviewer, this leaves a positive impression.
Tip 4 : Search and practice questions specific to the company, questions are repeated several times.
Tip 5 : A sound knowledge of Microsoft Azure Services and cloud computing will be an icing on the cake, and increase your chances to get selected.
Tip 6 : Keep giving contests on coding platforms, it will help you to stay motivated and check your stand.
Tip 7 : Keep a daily goal of number of questions instead of the time duration.
Tip 1 : Everything mentioned on the resume should be thoroughly known to you since if they catch you being dishonest, pretty good coding skills also might not help.
Tip 2 : Have projects related to the same field you are trying to apply for mentioned in your resume, this shows you are already experienced in the field.
Tip 3 : Adding references of some experienced people of the same field might help you gain their trust.
Tip 4 : Do not keep your resume too long, and do not mention irrelevant details, keep it short and crisp.
Tip 5 : Some experience in the field of operations and management or some positions of responsibility will really help you score extra points since it shows you have leadership qualities and are familiar with the market along with super coding skills.
I approached this problem in three steps -
(i) Search all positive integers, starting from 1 in the given array. We may have to search at most n+1 numbers in the given array. So this solution takes O(n^2) in the worst case.
(ii) Used sorting to solve it in lesser time complexity. We can sort the array in O(nLogn) time. Once the array is sorted, then all we need to do is a linear scan ...
