Morning : Data structures
Evening : practice C programs
Harry bhai on fire 🔥🔥🔥

[asmereg]

After writing the whole code for traversal, Harry be like "bilkul nhi bataunga ye aapko main".🤣🤣🤣🤣🤣

[prathamIsOp]

Solution to problem in C:
#include <stdio.h>

void traversal(int arr[], int n)
{
// traversal of arrays
for (int i = 0; i < n; i++)
{
printf("%d ", arr[i]);
}
printf("\n");
}

int indexInsertion(int arr[], int size, int element, int capacity, int index)
{
// code for inserting elements
if (size >= capacity)
{
return -1;
}
for (int i = size - 1; i >= index; i--)
{
arr[i+1]=arr[i];
}
arr[index] = element;
return 1;
}

int main()
{
int arr[100] = {1, 2, 3, 4, 5, 6, 7, 8};
int size = 8, element = 45, index = 5, capacity = 100;
traversal(arr, size);
int result = indexInsertion(arr, size, element, capacity, index);
if (result == 1) {
size++;
traversal(arr, size);
} else {
printf("Error: could not insert element\n");
}
return 0;
}

Dude you are literally gonna bring a coding revolution 😅
Hats off to you for doing this noble work✌✌

Love you Harry sir...❤

harry bhai bahut kuch seekhne ko mila hai aapse...lockdown ka full faida utha rha hun...COLLEGE SE JYADA TO AAPNE SiKHAYA HAI PROGRAMMING 💕💕😃

[harshitachaurasia]

Thank you for uploading this valuable content...
It is taking me to think deeper now!

[atharvakulkarni]

Bro You Are Amazing. Thanks for the great content that you provide..Please i have a request please can you implement these data structures in c++ because most probably in interviews most of the people use c++ to code and it would be great if you do so.

[sidhantjha]

// Code In C++
#include<iostream>
using namespace std;
void display(int arr[], int n){
for (int i = 0; i < n; i++)
{
/* code */
cout<<arr[i]<<" ";
}

}
int ind_insertion(int arr[], int size, int element, int capacity, int index){
if(size>=capacity){
return -1;
}
for (int i = size-1; i>=index; i--)
{
/* code */
arr[i+1]=arr[i];
}
arr[index] = element;
return 1;
}
int main(){
int arr[100] = {7, 8, 12, 27, 88};
int size = 5, element = 45, index = 1;
display(arr, size);
cout<<endl;
size += 1;
int check_display = ind_insertion(arr, size, element, 100, index);
if(check_display == 1){
cout<<"Display Successful"<<endl;
display(arr, size);
}
else{
cout<<"Insertion Failed "<<endl;
}
return 0;
}

14:27
int flag = indInsertion(arr, size, element, 100, index);
size += 1;
if ( flag == 1 )
display(arr, size);
else
printf("Insertion failed!!");

[Question]

Data structure notes are 🔥🔥🔥
Data structure vidoes🔥🔥🔥🔥

[amitrao]

Firstly, thank you so much harry bhai❤❤ for providing free and bestest lecture.. I have question can i use c++ instead of c??? I'm preparing for competitive programming.

[bigbossottupdate]

Wow! Today's video is here.. Good timing harry sir.

[manwtf]

This code has a bug.
For example if we have an array = {1, 2, 3, 4, 5} and the max capacity is 10,
if we insert an element, lets say 8, at index 7 the array will become {1, 2, 3, 4, 5, 0, 0, 8}, now the array has 8 elements, but since the size counter only increased by one, therefore, when we use display function, the output will be 1, 2, 3, 4, 5, 0

This is what I came up with to fix this problem:

#include <iostream>

void display(int *arr, int size)
{
std::cout << "Array: ";
for (int i = 0; i < size; i++)
{
std::cout << arr[i] << ' ';
}
std::cout << std::endl;

}

int indInsert(int *arr, int index, int *size, int capacity, int value)
{
if((*size) >= capacity || index >= capacity)
{
std::cout << "Insertion failed." << std::endl;
return -1;
}

else if (index > ((*size) - 1))
{
arr[index] = value;
(*size) = index + 1;
std::cout << "Insertion successfull." << std::endl;
return 0;
}

else
{
capacity = (*size) + 1;
for (int i = (*size); (*size) >= index; (*size)--)
{
arr[(*size)] = arr[(*size) - 1];
}
arr[index] = value;
(*size) = capacity;
std::cout << "Insertion successfull." << std::endl;
return 0;
}
}

int main()
{
int arr[10] = {1, 2, 3, 4, 5};
int size = 5;

display(arr, size);
if(!(indInsert(arr, 7, &size, 10, 8)))
{
std::cout << "Updated array: ";
display(arr, size);
}

return 0;
}

Output:
1 2 3 4 5
Insertion successfull.
1 2 3 4 5 0 0 8

This code is not the best because I am still a beginner.

[chilledfries]

this is motivating me to write better code EVERYDAY!!!!

[abeermoeed]

you are the coolest coder on the block!
you are in my prayers! thank you so much ^_^

[shubhamvalmiki]

harry bhai aap insan hi ho n aap ko kya kuchh nhi aata yrr kitne talented ho aap love you

[rachanakushwaha]

Really most valuable video Thanks Harry Sir for notes😊
