Basic Maths for DSA | Euclidean Algorithm | Strivers A2Z DSA Course

Full Course: takeuforward.org/strivers-a2z...
There is a slight mistake on the logic of Armstrong, it will be 1634 = (1^4 + 6^4 + 3^4 + 4^4), basically digits raised to the power count of digits, so sum = sum + pow(ld, cntDigits) will be the change, where the cntDigits is the number of digits.

The though topics are fully covered, so stop crying, I will upload at my speed, because I have a full time job, its not easy to work 9 hours and then create content.

For all those that couldnt get the 1634 test case right in the armstrong questoin, the power of each digit is equal to the no. of digits in the number for example : if it is a 4 digit number (1634) , then (1^4)+(6^4)+(3^4)+(4^4)=1634 if it is 3 digit then instead of 4 power will be 3 heres the code: #include bool checkArmstrong( int n) { string digits=to_string(n); int digitcount=digits.size(); int num=n; int r=0; int pal=0; while(n>0) { r=n%10; pal=pow(r,digitcount)+pal; n=n/10; } if(pal==num) { return true; } else return false; } might not be optimal but it is how i tried and it works

[@Iammuslim947]

yeah u r right even i got this mistake in most of the google search results but chatgpt and gfg gave me the right answer

[@MemoryFlick]

is this correct as well ?? what about time complexity??? { int i=0; int N = 371; int duplicateOfN1 = N; int d2 = N; while(N>0) { N=N/10; i++; } int sum = 0; int digitcount=i; while(duplicateOfN1>0) { int lastdigit = duplicateOfN1%10; duplicateOfN1 = duplicateOfN1/10; sum = sum+((int)Math.pow(lastdigit, digitcount)); } if(sum==d2) System.out.println("it is an armstrong number"); else System.out.println("it is not an armstrong number"); }

[@manishagrawal7104]

Actually power =number of digits in the number so try with power 4 it will work .

I'm from Andhra Pradesh, when I decided to learn DSA I searched a lot of streams, but I'm still stuck somewhere. After Watching your videos, it's just awesome. It very much helpful to beginners like me.... Thank you so much sir. After this I'm become a fan of striver......

[@karanbhoi5895]

23:55 One correction !! Armstrong number is the number in any given number base, which forms the total of the same number, when each of its digits is raised to the power of the number of digits in the number. 1634 is not equal to 1^3 + 6^3 + 3^3 + 4^3 it is equal to 1^4 + 6^4 + 3^4 + 4^4

[@chicha8482]

Can u provide the code for it am doing cmath and using pow function to use the number of powers equal to total no. Of digits but in 1634 its giving false

[@rajkumarvb5197]

[@Manishgupta200]

Striver your video is superb.. and in each video you taught in a very energetic way which makes your video very interesting. All the part in the video is amazing but the last.. i.e. Euclidean’s theorem and reducing loop by half by sqrt.. method is wonderfull.. Now, I try to build-up this type of logic in every Q. to reduce time & space complexity. Thankyou Striver ❤

[@rohanprabhakar1991]

Sir, you are helping me in doing hard work and making me experience the relief after doing the hard work we get Thanks for all your support Only have one request. I know you have been trying to make videos as fast as you can, but actually the placement is in the next 6-7 months, so if you can try to upload the beginner part as soon as possible, it would be beneficial to move for the other playlist of you which you have been uploaded in the past about different topics. Thank you for all the resources bhaiya(sir).
