[KaalHarMahadev]

this is the best thing you have that mistakes happen by everybody but other youtube teachers crop that part and you don't do that
such a great teacher

[sunilkumar_vlogs]

This question is simple, but it teaches me how to think deeply for solving problems. Thanks sir ji... still best course in 2025

[Kafi_relatable]

we can simply convert the integer to string and print the lenght line wise

[anonymous_aadmi]

❤❤❤better than most of the Paid Courses

[nishant_bhardwaj]

Why to use 'temp' instead on 'n' in number of digits in a number loop... When I am using just 'n' my result is 0.
Anybody has answer?

[PrinceRaj-tmrv]

Sir iss questions me pehale zero Hoga toh ye error aarha hai

[dhanrajpatil]

Sir where is your compiler where you write your code
I have checked the java foundation course open compiler but it's not like that
Mean when I use scanner class it throws error

[AdityaSingh-imiv]

sir agar aap suru se dry run karke dikha skte hai to or ache se smjh ata

[divyanshupandey]

String numString=String.valueOf(n);
int length=numString.length();
for (int i=0;i<length;i++) {


}

[abhishekbhadauriya]

why pow(10, 2) give 99 instead of 100 when used to store in int, this same goes for 2, 4, 8 exponents but not for 6 like pow(10, 4) give 9999 and pow(10, 6) give and again pow(10, 8)give (c++) why?

[adnanmakkiofficial]

sir thoda basics to bhi bta diya kriye hm log begginers hain sb upr se jata hai for example intmath.pow ye nhi smjh aa khn se use kis liye use hua

[justseethis-]

any one can tell me why sir used n=n%div; in second loop. please tell me.

[deeptomar]

private static List<Integer> getTheDigits(int num)
{
ArrayList<Integer> allData = new ArrayList<>();
while (num>0)
{
//% will always gives us remainder
allData.add(0, num %10);
num = num /10;
}
return allData;
}

sir..is it okay to do like this

[mohitratanpal]

Mza agya sir ye q krke, dimaag khulgya

[slowedReverbJunction]

Sir I have used for loop in this and it shows time limit exceeded

[adityawable]

why this line is giving error in python editor? any ideas guys?

[RishabhSharma-tprs]

Sir how to write div = 10^nod-1; in c++

[tejaswikumar]

sir i am not able to solve the questions without watching the solution video.
is it normal if yes
then kindly guide me to overcome this.

[gurpreetsinghdua]

Sir this is how i did it:

import java.util.*;
import java.lang.Integer;
public class Main{

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
String s = Integer.toString(n);
for(int i = 0 ; i <s.length();i++){

}
}
}
