I have been coder for last 10 years and always feared of DSA. But after following Kunal's course I have gained so much of confidence. Its like I have re-learnt everything with different approach. Every problem can be solved multiple ways but Kunal's ways are super easy ways I must say. Going to follow complete DSA series. #DSAwithKunal

No amount of words can express how fortunate I’m that I landed up to Kunal’s DSA preparation course… the way he teaches by providing every minute details & simplifying our thought process is beyond words. As intended you’re creating a revolution in history of DSA. PS: it will only cost ur valuable time & no other paid course will ever teach u the tricks the way Kunal did!!! #DSAwithKunal

I start watching your VDO, I think the examples are good and creative. I can add something to apply to my study. Patterns solving is problematic thinking when you can re-create into new equation as N = wX + q for the recursive problem. How you determine the next number from the data rows from previous data input. ( Inside AI they use sample layer as this N = wX + q for dense layer ) You can do more than symmetric shape patterns.

Great Explanation.. Loved it 17:30 for Pattern 3, I did it the below way public static void PrintPattern1(int n) { for (int row = 1; row = 1; col--) { Console.Write("* "); } Console.WriteLine(); } } 19:00 for Pattern 3, focus on the numbers written by Kunal.. n = 4. rows are like this 1, 2, 3, 4 and columns are like 4, 3, 2, 1 which is reverse (i.e., columns starts from n and reduces to 1) But if we directly use variable n and decrease its value in outer forloop, no.of rows will decrease, so better to store n value in one variable and reduce the value of that variable in each outerloop. Below code explains this approach public static void PrintPattern1AnotherWay(int n) { int iterations = n; for (int row = 1; row
