内容位置 → 极限依据Candidate from reviewed en material v1: For an ordinary finite two-sided limit on a real interval around the target, both finite one-sided limits must exist and equal the same number. Agreement gives the two-sided limit; disagreement rules it out. This exercise has unequal finite values.
内容位置 → 极限依据Candidate from reviewed zh material v1: 对于目标附近实数区间上的通常有限双侧极限，两侧的有限极限必须存在且等于同一个数。相等时得到双侧极限；不相等时双侧极限不存在。本题两侧有限值不同。
