I had an interview today, I was asked how search for a number inside an array, I said binarysearch, he asked me how about a big array that has thousands of bjects (for example Stocks) searching for example by price of the stocks, I said binarysearch again, he said sorting an array of thousands will take lot of time before applying binarysearch.

Binary search algorithm - Wikipedia

★ ★ ★ ★ ☆

Binary search runs in logarithmic time in the worst case, making O (log n) comparisons, where n is the number of elements in the array, the O is Big O notation, and log is the logarithm. Binary search takes constant ( O (1) ) space, meaning that the space taken by the algorithm is the same for any number of elements in the array. [6]

The worst-case time for binary search is proportional to log 2 N: the number of times N can be divided in half before there is nothing left. Using big-O notation, this is O(log N). Note that binary search in an array is basically the same as doing a lookup in a perfectly balanced binary-search tree (the root of a balanced BST is the middle value).
