STL中vector和array的比较 了一个新的容器std::array,该容器在某些程度上替代了之前版本的std::vector的使用,更可以替代之前的自建数组的使用。那针对这三种不同的使用方式,先简单的做个比较: 相同点:1.三者均可以使用下表运算符对元素进行操作,即vector和array都针对下标运算符[]进行了重载2.三者在内存的方面都...

print(two_D_vector);//sorting the 2D array based on a particular row//here we sort the last row of the 2D vector//in descending order//so, basically we sort the 1D array in//descending order(the last row)sort(two_D_vector[2].begin(), two_D_vector[2].end(), greater<int>())...
This is yet another example of a problem in which the required solution is an array of arrays. Something that, as specified, lies outside the scope of Excel. However, although XLOOKUP will not return an array of arrays, INDEX will return the equivalent 2D array. So annoying...

sort()可以对当前Array进行排序,它会直接修改当前Array的元素位置,直接调用时,按照默认顺序排序var arr = ['B', 'C', 'A']; arr.sort(); arr; // ['A', 'B', 'C']reverse()把整个Array的元素给掉个个,也就是反转var 元素 原创 Ansue 2015-12-23 11:35:26 378阅读 swift...
