就是找x+y=-z的组合 转化为找出值为-z满足x+y=-z的组合 解法一: 为了查找,首先想到排序,为了后面的二分,nlogn, 然后x+y的组合得n^2的复杂度,加上查找是否为-z,复杂度为nlogn + n^2 * logn 解法二: 还是先从小到大排序 nlogn 假设数组排序后为 a b c d e f 我们还是要找x+y=-z 会发现-z存在的可能只能是a+f和b+e,不会存在a+e和b+f这种情况(这里很重要,保证了算法的正确性),所以两个指针一头一尾往中间扫,肯定能找出来 fis
ArcGIS API for JavaScript根据两个点坐标在地图上画线比如说a(xxxx,xxxxx),b(xxxx,xxxxx).利用这两个点画一条线 var polyline = new esri.geometry.Polyline([[xxx,xxx],[xxx,xxx]]); var symbol = new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([
import re x, y, z = re.split(',| |,| ', input('请输入3个数字,用逗号或空格隔开:'))x, y, z = int(x), int(y), int(z) maxNo = max(x, y, z)minNo = min(x, y, z)print(maxNo, x+y+z-maxNo-minNo, minNo) # 方法二 用 re.split() 得到 3 个字符型数字的列表,把字符转换为数字,排下序,然后 print() 代码如下:import r
‘,’之后要留空格,如 Function(x, y, z).如果‘;’不是一行的结束 符号,其后要留空格,如 for (initialization; condition; update). #include <iostream> /* run this program using the console pauser or add your own getch, system("pause") or input loop */ using namespace std; /
