algo/scheduling

calc row grouping of Gantt chart

import scheduling from '@elzup/kit/lib/algo/scheduling'
const items = [
  { id: 'a', start: 1, end: 10 },
  { id: 'b', start: 5, end: 15 },
  { id: 'c', start: 10, end: 20 },
  { id: 'd', start: 12, end: 20 },
  { id: 'e', start: 16, end: 17 },
]

scheduling(items)

// [['a', 'c'], ['b', 'e'], ['d']]

if need gaps (add margin to end)

scheduling(items.map((v) => ({ ...v, end: v.end + 1 })))
// [['a', 'd'], ['b', 'e'], ['c']]
