Paul King updated GROOVY-11654:
-------------------------------
Description:
When creating potential examples for the Groovy 5 release notes, I created this
example:
{code:groovy}
// keep top 5 scores in top array
int[] scores = [56, 82, 70, 74, 63, 92, 49, 69, 85, 79, 80, 82, 99, 95]
int[] top = scores[0..4].sort()
scores[5..-1].each { next ->
def ins = top.partitionPoint{ it < next } - 1
if (ins > 0) {
System.arraycopy(top, 1, top, 0, ins)
// top[0..<ins] = top[1..ins]
}
if (ins >= 0) {
top[ins] = next
}
}
assert top == [82, 85, 92, 95, 99]
{code}
The {{System.arraycopy()}} line would be {{top[0..<ins] = top[1..ins]}} if
using lists. It would be nice if arrays supported putAt and that line didn't
need to change.
