1. What is a folding list in Scala?

Folding a list in Scala is the process of creating a single result by applying a binary operator to each list member and a starting value. The list is reduced to a single value by this procedure....

2. Explain foldLeft along with code.

The foldLeft function in Scala’s collections iterates from left to right across a collection’s items, applying an accumulator and a binary operation to each member. It has the definition (z: B)(op: (B, A) => B): B, where op is the binary operator and z is the starting value....

3. Explain foldRight with code.

foldRight folds components from the right to the left; it works similarly to foldLeft....

4. Explain fold.

Any kind of collection may be folded using the generic folding technique called fold. Both the starting value and the binary operator may be specified....

5. Explain the Difference using Parallelism and Method Signature.

The evaluation sequence and possible use of parallelism are the primary distinctions between foldLeft, foldRight, and fold:...

6. Conclusion

In Scala, folding lists provide a clear and effective method for carrying out aggregate calculations on collections. It is essential to comprehend the distinctions between foldLeft, foldRight, and fold when designing understandable and effective code....
