The first() method returns the first matching document. For more information on querying MongoDB with the Java driver, see our guide on Querying Documents. You can also chain other methods to the find() method such as sort() which organizes the matched documents in a specified order, and ...
如果想要得到所查找的元素在查找区间中的下标,则需要用find()函数返回的地址减去起始地址,即find(a,b,data)-a,从而得到data元素在[a,b)区间中的下标(相对位置)。 代码案例 代码语言:javascript 代码运行次数:0 运行 AI代码解释 #include<iostream>#include<algorithm>using namespace std;intmain(){int a[6]...
out.print ("Single digit elements present in the array are: "); //take a for loop to find the single digits in first array for (int i = 0; i < inputArray1.length; i++) { //in each loop find the modulus value with 10 //so that we can find the single digit value if (...
Java Program to find the Last Index of a Particular Word in a String - In Java, a string is also an object. It is the object of the String class. A String is a sequence of characters. The last index of a particular word in a string is nothing but the pos
