方法/步骤 1 首先建立一个名称为array_unique的php页面。2 在页面中声明一个数组变量。3 再声明一个数组变量arr1 4 创建一个数组并赋值给变量 5 将arr放入到array_unique函数中将返回的值赋值给arr1 6 分别打印两个数组并做对比，结果arr中两个重复的值被清除。
example:include <iostream>#include <cassert>#include <algorithm>#include <vector>#include <string>#include <iterator>using namespace std;int main(){//cout<<"Illustrating the generic unique algorithm."<<endl;const int N=11;int array1[N]={1,2,0,3,3,0,7,7,7,0,8};vector<...

This state-of-the-science volume brings together an array of leading authorities to comprehensively review theory and research in this burgeoning area. MR Leary,JP Tangney - 《Psychiatric Services》 被引量: 1682发表: 2003年 The psychology of careers : an introduction to vocational development The ...
该函数的语法为:UNIQUE(array, [by_col], [exactly_once]) 其中,array 表示需要筛选唯一值的数据范围;by_col 为可选参 数,表示是否按列进行筛选,默认为 FALSE,表示按行筛选; exactly_once 为可选参数,表示是否仅保留出现一次的值,默认为 FALSE,表示不限制出现次数。 使用 UNIQUE 函数可以实现以下功能: 1. ...
Maxim. were simultaneously quantified by high‐performance capillary electrophoresis with diode‐array detector to assess the effect of extraction technology. The optimal extraction parameters were determined as: the concentration of ethanol 56.21%, liquid/solid ratio 14.65:1, and extraction time 1.64 h ...
Difference is reflected by the difference of array of the envelope gene, uses these differences, can offer nuclear acid and the antibody probe which can distinguish these two sub- dies. Because of this, transmission of intercellular sub- die (from the especially cover cell) it becomes possible ...
使用numpy的array创建一个包含8个元素的一维数组,正确的代码为: A.np.array([12,34,5,6,7,8]) B.np.arange(8) C.np.arange(7) D.np.array([1,2,3,4,5,6,7,8]) 单项选择题 要禁止8259A的IR0的中断请求,则中断屏蔽操作指令字OCW1应为()。
$a=array("a"=>"red","b"=>"green","c"=>"red"); print_r(array_unique($a)); ?> 运行实例 » 定义和用法 array_unique() 函数用于移除数组中重复的值。如果两个或更多个数组值相同,只保留第一个值,其他的值被移除。
移除数组中重复的值的函数是( )?A.array array_unique ( array $array [, int $sort_flags = SORT_STRING ] )B.array unique ( array $array [, int $sort_flags = SORT_STRING ] )C.array str_unique ( array $array [, int $sort_flags = SORT_STRING ] )D.array array_delete ( array $...
