Hey! Say I have an arbitrary List<Int> where every entry is a counter. What would be a Kotlin-esque way to map this into a List<Int> where at every index the entry is equal to the sum of counts until that index? For example, [1, 3, 4, 2, 2] becomes [1, 4, 8, 10, 12] due to the following summations: [1, 1+3, 1+3+4, 1+3+4+2, 1+3+4+2+2]

A fold should do the trick, passing through the resulting list and the current accumulated value https://pl.kotl.in/wJudkD4RI
