Why can't you use this for the comparison operator: bool operator<(const interval& x, const interval& y) { if x.min < y.min return true; if x.min

Why can't you use this for the comparison operator:
bool operator<(const interval& x, const interval& y)
{
if x.min < y.min return true;
if x.min > y.min return false;
return x_max < y.max;
}
- mgaunard 1y agobetter implemented as tie(x.min, x.max) < tie(y.min, y.max)

- Sharlin 1y agoThat’s fine if you just need any well-defined SWO, but I presume the author needs this specific ordering for some algorithmic reason. Still, it’s pretty ugly for a comparator to be throwing.
