How to efficiently merge responses from multiple APIs, eliminating duplicates before displaying data?.

To effectively merge responses from multiple APIs and eliminate duplicates, you can use the following approaches:

1. Collect all data into a single collection (e.g., a list).
2. Define criteria for the uniqueness of elements (e.g., a unique ID or a combination of fields).
3. Use data structures that automatically exclude duplicates, such as Set.
4. If necessary, implement merging logic when duplicates contain different information.

Example in Kotlin for Android:

val apiResponse1 = listOf("apple", "banana", "orange")
val apiResponse2 = listOf("banana", "kiwi", "apple")

// Merge and remove duplicates
val combined = (apiResponse1 + apiResponse2).toSet().toList()

println(combined) // Will output: [apple, banana, orange, kiwi]

Thus, before displaying the data, you get a unique set of elements without repetitions.
