Search an element in a sorted and pivoted array Question: An element in a sorted array can be found in O log n time via binary search. But suppose I rotate the sorted array at some pivot unknown to you beforehand. So for instance, 1 2 3 4 5 might become 3 4 5 1 2. Devise a way to find an element in the rotated array in O log n time.

An array is a collection of items stored at contiguous memory locations. The idea is to store multiple items of the same type together. This makes it easier to calculate the position of each element by simply adding an offset to a base value, i. The above image can be looked as a top-level view of a staircase where you are at the base of the staircase. Each element can be uniquely identified by their index in the array in a similar way as you could identify your friends by the step on which they were on in the above example.

For example , if we have to store the marks of 4 or 5 students then we can easily store them by creating 5 different variables but what if we want to store marks of students or say students then it becomes very challenging to create that numbers of variable and manage them. Now, arrays come into the picture that can do it easily by just creating an array of the required size. We can initialize an array at the time of declaration or after declaration. We have initialized the array with values. Here, 1 is stored in arr[0], 2 in arr[1], and so on.
