It was 1 coding question with 10 test cases. They asked a question based on binary search. I got 3 hrs to clear that test. I went in as a campus fresher. For lateral joinees, it is a much more difficult question that you have to clear in 4hrs.
The best way to find the majority element in an array is by using the Boyer-Moore Voting Algorithm.
Initialize a candidate variable and a count variable.
Iterate through the array and for each element:
- If the count is 0, set the current element as the candidate.
- If the current element is the same as the candidate, increment the count.
- Otherwise, decrement the count.
After the iteration, the candidate will be the ...
