4.1 1D-Array 1. One-dimensional array 1D-array is a limited sequence composed of n (n20) elements which are of the same data type. For example:

一、判断题:(正确打√,错误打×)(共10分) 1.C语言中的局部静态变量是在动态存储区内分配的。 2.带有叶节点的二叉树的前序遍历序列与中序遍历序列不可能相同。 3.一个有序表的折半查找,当表长n较大时,平均查找长度是In(n) 4.下面是二维数组的说明:

1. Early studies on the peptide(protein) structure 1.1 The peptide(o=c-n-h) bond was found to be shorter than the C-N bond in a simple amine and atoms attached are coplanar. 1.1.1 This was revealed by X-ray diffraction studies of amino acids and of simple dipeptides and tripeptides

一、概念: 1.级数:级数,无穷级数;通项(一般项,第n项),前n项部分和等概念(与中学的有关概念联系)级数常简记为∑un
