#Algorithm: Detect duplicate elements in Array

Also Check: Algorithms and System Design Interview Questions

How to detect duplicate elements in Array in Java?
1). Brute Force: In this approach we will compare each element of Array to all other elements and returns true if it founds duplicates. FYI, this is not an efficient choice.

2). Using HashSet: If you just need to find if whther the array has duplicates of not, convert that array into Set. Since Set doesn’t allow duplicates, the size of the corresponding Set will be smaller than the original Array if Array contains duplicates otherwise the size of both Array and Set will be the same.

Solution 1:
Queue has FIFO, but Stack is FILO. We will use two queues q1 and q2. We can make sure that newly entered element is always at the front of q1, so that pop operation just dequeues from q1. q2 is used to put every new element at front of q1.

#LeetCode: Maximum consecutive one's

Also Check: LeetCode Solutions in Java

Let's say we want to find maximum consecutive one’s in a binary array.

Algorithm:
1). Maintain two counters current and max.
2). Start iterating the array, if 3.a). the current number is 1, we need to increment 'current'.
3). If the current number is 0, then we need perfom below checks:
3.a) If the 'current' is greater than 'max', we set 'current' in 'max'.
3.b). If max is greater than equal to half of array length, so we should return max as there is no point in checking the array further.
3.c). Set the 'current' as zero.
4). Return 'current' or 'max', which ever is higher.
