• curprev 10:4410:44, 12 October 2017‎ Rainwarrior talk contribs‎ 3,078 bytes −114‎ →‎frantik: it seems more responsible just to fix the infinite loop case than add a warning about it

• curprev 10:3610:36, 12 October 2017‎ Rainwarrior talk contribs‎ m 3,194 bytes −28‎ shouldn't try to reason about "average", even if the distribution of inputs was uniform, the distribution of values isn't, so the midpoint of high and low isn't really a good average either

• curprev 06:0706:07, 12 October 2017‎ Rainwarrior talk contribs‎ 2,627 bytes +112‎ fixing comment alignment (tabs should only be used to align the left column, not mid-line, because variable tab widths breaks this)
• curprev 06:0306:03, 12 October 2017‎ Rainwarrior talk contribs‎ 2,515 bytes +618‎ both of these methods are technically "russian peasant", trying to rewrite their descriptions
