# How to Sum All Elements Of Queue In Kotlin?

To sum all elements of a queue in Kotlin, you can create a variable to hold the sum and iterate through all elements in the queue using a while loop or a forEach loop. For each element in the queue, add it to the sum variable. Once you have iterated through all elements, the sum variable will contain the total sum of all elements in the queue.

## What is the function to find the maximum element in a queue in kotlin?

There is no built-in function in Kotlin to find the maximum element in a queue. However, you can manually iterate through the queue and keep track of the maximum element yourself. Here is an example of how you can do this:

 ``` 1 2 3 4 5 6 7 8 9 10 11 ``` ```fun findMaxInQueue(queue: Queue): Int? { var maxElement: Int? = null for (element in queue) { if (maxElement == null || element > maxElement) { maxElement = element } } return maxElement } ```

You can call this function and pass in a queue of integers to find the maximum element in the queue.

## What is the difference between a queue and a stack in kotlin?

In Kotlin, a queue and a stack are both data structures used to store and retrieve elements in a particular order, but they have different characteristics.

Queue:

1. A queue is a linear data structure that follows the First In First Out (FIFO) principle, meaning that the element that is added first will be the first one to be removed.
2. Queues are typically used for implementing tasks such as scheduling, buffering, and order processing.
3. In Kotlin, queues are commonly implemented using classes such as LinkedList or ArrayDeque from the Java Collections Framework.

Stack:

1. A stack is a linear data structure that follows the Last In First Out (LIFO) principle, meaning that the element that is added last will be the first one to be removed.
2. Stacks are typically used in situations where the order of retrieval matters, such as in function call management and expression evaluation.
3. In Kotlin, stacks can be implemented using the MutableList interface or the ArrayDeque class from the Java Collections Framework.

In summary, the main difference between a queue and a stack in Kotlin is the order in which elements are added and removed. Queues follow the FIFO principle, while stacks follow the LIFO principle.

## What is the function to check if a specific element is in a queue in kotlin?

The function to check if a specific element is in a queue in Kotlin is `contains(element: E): Boolean`, where `element` is the element you want to check for in the queue and the return value is a boolean indicating whether the element is present in the queue or not.
