The odd values in a list can be calculated by knowing the first and last number, whereas even numbers can be divided by two and the remainder is zero (0).
<h3>What are even numbers and odd numbers?</h3>
The even numbers can be found in a list because they are divisible by two and the remainder of this equation is always zero (0).
Conversely, odd numbers are those that cannot be divided exactly into exact entire numbers (e.g., 3, 5, etc).
The odd numbers in a list can be calculated by the equation ON (odd numbers): n/2 × [f + g], where 'f' is the first number and 'g' is the last number.
In conclusion, the odd values in a list can be calculated by knowing the first and last number, whereas even numbers can be divided by two and the remainder is 0.

Keira is using the software development life cycle to create a new app. She has the pseudocode for her program. The next stage for Keira is CODING.
Explanation :
- SDLC or the Software Development Life Cycle is a process that produces software with the highest quality and lowest cost in the shortest time. SDLC includes a detailed plan for how to develop, alter, maintain, and replace a software system.
- SDLC involves several distinct stages, including planning, design, building, testing, and deployment. Popular SDLC models include the waterfall model, spiral model, and Agile model.
- The steps of the SDLC are given below :
- Identify the current problems. “What don’t we want?”
- Plan. “What do we want?”
- Design. “How will we get what we want?”
- Build. “Let’s create what we want.” This SDLC stage develops the software by generating all the actual code. If the previous steps have been followed with attention to detail, this is actually the least complicated step.
- Build is the phase which Keira should move onto in the SDLC
- SDLC done right can allow the highest level of management control and documentation. Developers understand what they should build and why. All parties agree on the goal up front and see a clear plan for arriving at that goal. Everyone understands the costs and resources required.
Answer:
Option (A)
Explanation:
In the post order traversal, we always print left subtree, then right subtree and then the root of the tree. In preorder traversal, First the root is printed, then, left subtree and at last, right subtree, so, the first element in preorder is the root of the tree and we can find elements of left sub tree from in order as all the elements written left to the root will of left subtree and similarly the right one. This is how repeating it will give the post order traversal.
