Reductions

Find the incremental values of a sequence "reduce" operation.

Overview

Call one of the reductions methods when you want the result of a reduce operation along with all of its intermediate values:

swift
let exclusiveRunningTotal = (1...5).reductions(0, +)
print(exclusiveRunningTotal)
// prints [0, 1, 3, 6, 10, 15]

let inclusiveRunningTotal = (1...5).reductions(+)
print(inclusiveRunningTotal)
// prints [1, 3, 6, 10, 15]
