associateFirst

inline fun <T, K, V> Sequence<T>.associateFirst(key: (T) -> K, value: (T) -> V): Map<K, V>

Returns a Map containing key-value pairs provided by key and value functions applied to elements of the given sequence.

If any of two pairs would have the same key the first one gets added to the map.

The returned map preserves the entry iteration order of the original sequence.
