Kotlin filter nested lists
I want to filter a list that has episodes of series. The list looks a bit like this:
[
{
"media": {
"episode_number": "7"
},
"collection": {
"collection_id": "26464"
}
},
{
"media": {
"episode_number": "6"
},
"collection": {
"collection_id": "26464"
}
},
{
"media": {
"episode_number": "9"
},
"collection": {
"collection_id": "123456"
}
}
]

I only want the highest episode number of each collection...
