Here we shall discuss a C++ Program to find number of ways to Partition a word in such a way that each word is a Palindrome.AlgorithmsBegin    Take the word as input.    Function partitionadd(vector &u, string &s, vector &tmp, int index):    if (index == 0)       ... Read More

You need to set numericOrdering: true for alphanumeric sort. Let us first create a collection with documents −> db.alphanumericSortDemo.insertOne({"StudentId":"STU1010"}); {    "acknowledged" : true,    "insertedId" : ObjectId("5ccf149adceb9a92e6aa194c") } > db.alphanumericSortDemo.insertOne({"StudentId":"STU1101"}); {    "acknowledged" : true,    "insertedId" : ObjectId("5ccf14a2dceb9a92e6aa194d") } > db.alphanumericSortDemo.insertOne({"StudentId":"STU1901"}); {    "acknowledged" : true,    "insertedId" ...

You can use $setIntersection for this. Let us first create a collection with documents −> db.setInterSectionDemo.insertOne( ...    {"_id":101, "Value1":[55, 67, 89]} ... ); { "acknowledged" : true, "insertedId" : 101 } > db.setInterSectionDemo.insertOne( ...    {"_id":102, "Value2":[90, 45, 55]} ... ); { "acknowledged" : true, "insertedId" : 102 } ...

This mbrtowc() function is used to convert multibyte sequence to wide character string. This returns the length of the multibyte characters in byte. The syntax is like below.mbrtowc (wchar_t* wc, const char* s, size_t max, mbstate_t* ps)The arguments are −wc is the pointer which points where the resulting wide character ... Read More

Let us first create a collection with documents −> db.matchingFirstItemInTheArrayDemo.insertOne(    {       "ClientDetails": [          {             "ClientName": "Larry",             "ClientAge":28          }       ]    } ); { ... Read More

In this section, we will see how to use the catch block for exception handling and the type conversion in C++.At first, let us see a code, and we will see what will be the output, and how they are generating.Example#include using namespace std; int main() {    try{ ... Read More

Let us first create a collection with documents −> db.multipleConditionDemo.insertOne({"_id":1, "Name":"John"}); { "acknowledged" : true, "insertedId" : 1 } > db.multipleConditionDemo.insertOne({"_id":2, "Name":"Carol"}); { "acknowledged" : true, "insertedId" : 2 } > db.multipleConditionDemo.insertOne({"_id":3, "Name":"Sam"}); { "acknowledged" : true, "insertedId" : 3 } > db.multipleConditionDemo.insertOne({"_id":4, "Name":"David"}); { "acknowledged" : true, "insertedId" : ...

To create Horizontal slider in Java, use the Swing JSlider. Let us first create a frame and a Horizontal slider in it −JFrame frame = new JFrame("Frame with Slider"); JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 70);Now, we will set the values for the slider. Display the ticks −slider.setMinorTickSpacing(5); slider.setMajorTickSpacing(20); ... Read More

Here we will see what are the differences between qsort() in C, and sort() in C++.The C provides qsort() function, that can be used for sorting an array. The function arguments and syntax is like below.void qsort(void *base, size_t num, size_t size, int (*comparator) (const void*, const void*));This function takes ... Read More
