We are up with the lecture 10 of our much awaited dsa course in java.
We are up with a new lecture in the mathematics module of our free dsa course. Today we will learn about how to find if a number is prime or not.
We will understand the complete logic behind prime number and what is the logic behind the program to find if a number is prime or not.
Finding whether a number is a prime number or not is a very popular programming question from the point of interview and every job aspirant must learn the concept behind this program.
In this lecture we will learn the complete logic behind the prime number identification program and the complete code in java as well.
Watch the complete lecture and add more expertise to your dsa learnings.

sir the time complexity for this cannn also be minimize to o(1) or o(4) by this if(num==1)return false; if(num==2||num==3||num==5)return true; if(num%2==0||num%3==0||num%5==0)return false; return true; }

Thank you sir, but I have a doubt is 35 prime? Because it's factors: 1,5,7,35 🤔🤔

Hi sir, at 4:42,you mentioned that the last factor is divided by 2. However, 2, 3, 4, 3, 5, 6, out of these highlighted numbers,2, 2, 5 are not divided by 2. Can someone please clarify where am I missing?

Till date this is the best video explanation I have seen on the analysis of prime number & how to find them in Java this video deserves the title of "fantastic primes and where to find them" 😅 This video perfectly explains the programming logic of finding primes whilst preserving the pure essence mathematical analysis ❤

This Logic does not work for higher numbers , it restricts you to lesser number only for Example 21 is divisible by 7 (7*3=21)

@nadeemmirza3245
