Solution 1 : Our first solution is very simple. All we are doing here is to loop over an array and comparing each element to every other element. For doing this, we are using two loops, inner loop, ...

##Given an integer array(ARR) of size N which contains numbers from 0 to (N - 2). Each number is present at least once. That is, if N = 5, the array constitutes values ranging from 0 to 3 and among ...

Python is convenient and flexible, yet notably slower than other languages for raw computational speed. The Python ecosystem has compensated with tools that make crunching numbers at scale in Python ...
