The is related to the concept of "sequence point". e.g.
a[i] = i++
because there is no sequence point specified for the assignment, increment
or index operators, you don't know when the effect of the increment on i
occurs.
Same reason for i++ + i++ |

想了一个O（n）的解法。请帮忙看一下对不对。
if A and B have no duplicate char: easy problem. just traverse C. increase A
's
index if A's char matches or increase B's index if B's char matches.
if A and B have duplicate chars, we assume A[i, j] == B[m, n].
when we traverse C and in the position where C[k] == A[i] == B[m], we have
two ways to go: increase A's index or increase B's index. in this kind of
situation, we will always select to increase A's index.
if we are lucky, A is the right way to ... 阅读全帖 |

发帖数: 344 | 49 实现一个increment an integer by 1的函数，the integer can be huge, 数据结构自选
e.g., [2,3,6] --> [2,3,7]
我一开始用ArrayList, 为的是方便处理最大数位进位的情况， e.g. 999 ->
1000。
后来经过提醒用char[]，这样计算前需要转换成int, 而且如果最大位数要进位需要重
新初始化一个char[] ... 不知道这样对吗？
关于increment()计算本身，我用iteration和recursive各写了一遍，主要考虑了进位
，不过没考虑负数 ... 不知道算不算一个bug？
唉，刚开始准备找工作就面了G家，心里好没底啊。希望好心人bless有个onsite吧 |
