Reorder elements within array by index.
const reorder = require('array-rearrange')
let arr = reorder([9,8,7,6], [3,2,1,0]) // [6,7,8,9]
let arr2 = reorder([3,3, 2,2, 1,1], [2,1,0]) // [1,1, 2,2, 3,3]
API
array = reorder(array, index, stride=1)
Shuffle elements in array
according to the index
array passed. Permutes original array. index
array should contain unique indexes. Pass stride
to indicate groups of elements to shuffle.
Originally based on the reference solution, which turns out to be wrong, so algorithm is fully rewritten.
