您需要拆分 [ ^ ]两个字符串到数组：

You need to split[^] both strings to arrays:

Array1                Array2
0    Hyderabad        Cybergateway
1    Chennai          hitech city
2    Pune             Hyderabad
3    Delhi            Telangana
4                     India

然后你需要比较它们[ ^ ]使用2个循环：

Then you need to compare them[^] using 2 loops:

First loop         Second loop            Result
0    Hyderabad     0    Cybergateway      False
0    Hyderabad     1    hitech city       False
0    Hyderabad     2    Hyderabad         True
0    Hyderabad     3    Telangana         False
0    Hyderabad     4    India             False
1    Chennai       0    Cybergateway      False
1    Chennai       1    hitech city       False
1    Chennai       2    Hyderabad         False
1    Chennai       3    Telangana         False
1    Chennai       4    India             False
2 ....
//and so on...

如果您对javascript更熟悉，可以使用 indexOf方法（数组）（JavaScript） [ ^ ] 。



详情请见：

数组对象（JavaScript） [ ^ ]

使用数组（JavaScript） [ ^ ]

If you're more familiar with javascript, you can use indexOf Method (Array) (JavaScript)[^].

伪算法看起来像这样



函数IdentifyCommonString（string srcString1，string srcString2）

{

var hashTable = new HashTable（）;

var sourceArray1 = srcString1.split（，）;

var sourceArray2 = srcString2.split（，）;

var arrayLength = sourceArray1.length;

for（var i = 0;我< arrayLength; i ++）{

var item = hashTable.get_item（sourceArray1 [i]）;

if（！item）

hashTable.set_item（item ，item）;

else {

//我们的常用字符串现已确定

alert（item）;

}

}



arrayLength = sourceArray2.length;

for（var k = 0; i < arrayLength; k ++）{

var item = hashTable.get_item（sourceArray2 [i]）;

if（！item）

hashTable .set_item（item，item）;

else {

//我们的常用字符串现已被识别

alert（item）;

}

}



}

Check this Hashtable implementation How do I implement a Dictionary or Hashtable in Javascript?[^]

The pseudo algorithm could look like this

function IdentifyCommonString(string srcString1, string srcString2)
{
var hashTable = new HashTable();
var sourceArray1 = srcString1.split(",");
var sourceArray2 = srcString2.split(",");
var arrayLength = sourceArray1.length;
for (var i = 0; i < arrayLength; i++) {
var item = hashTable.get_item(sourceArray1[i]);
if (!item)
hashTable.set_item(item, item);
else {
//our common string has now been identified
alert(item);
}
}

arrayLength = sourceArray2.length;
for (var k = 0; i < arrayLength; k++) {
var item = hashTable.get_item(sourceArray2[i]);
if (!item)
hashTable.set_item(item, item);
else {
//our common string has now been identified
alert(item);
}
}

}
