WebYou have two for loops, each iterating over the entire array. If the array has n elements, then the run time for your algorithm is O ( n2 ). (Even with the inner-loop optimization mentioned in the previous point, it would still be O ( n2 ).) For a small homework problem like this, that is perfectly acceptable, because simplicity is the main goal. WebAssume that there is only one duplicate number, find the duplicate one. Input: [1,3,4,2,2] Output: 2. 1.You must not modify the array (assume the array is read only). You must use only constant, O(1) extra space. Your runtime complexity should be less than O(n2). There is only one duplicate number in the array, but it could be repeated more ...
