--- Comment #29 from baoshan <pangbw at gmail dot com> --- > However, it is clear that _14 = baz[_9] is executed only 5 times (not 5 > times + 1). Why is this estimate wrong? The max value of n is 6, so the max value of i is 5 as "i < n", then the max value of j is 4 as "j = i - 1" which means the max iterate times is 4.
