Consider a sorted array of $k+1$ elements, where the elements are first $k$ natural numbers $-\left \{ 1, 2, 3, 4, 5,\dots, k \right \}$ and any one of those $k$ numbers is repeated. The time complexity of best algorithm to find that repeated number is: $O\left ( k \right )$ $O\left ( k\log k \right )$ $O\left ( \log k \right )$ $O(1)$
