Some questions and practical examples were legitimate, like multithreading behavior leading to zombie processes. Some were rather synthetic or just examples of bad code that you should never see anyway, like what would this do: int i = 5; int x =10; i+++++j;

Given an integer array and another number, find a pair whose sum is given number. Best solution is to use unordered map <int, int> then use this logic map[sum - a[i]] = a[i]; // O(n) then, for each a[i], if map[a[i]] present then that will be the answer. // O(n)
