Hey Striver, i think for the pattern 18, we should not directly start from 'E', I think according to pattern we should be starting form ('A' + n - i + 1) until ('A' + n), for(int i = 0; i < n; i++) { for(char ch = 'A' + (n - i - 1); ch < 'A' + n; ch++) { cout

[@damolaOnikoyi]

Thank you Striver, preciate ya!!. I just completed all the pattern problems. The last one was quite tricky as I did not quickly understand your solution. However, I have provided my solution below for others that might find it helpful and maybe easier to understand. Intuition: Fill the 2D array (named result) with the values (n, n-1, n-2 ...) then just simply print it out (row x column)👍🏾. You can fill the result array like this : 1. Outer loop fills the layer (A layer is a square ring of numbers). 2. Get the number to be filled per layer => int num = n - layer. Hence if n = 3, layer = 0 (first one) -> n , n - 1, n - 2 ... so we print 3, 2, & 1 per square ring. 3. Middle loop iterates over the rows of the current layer. 4. Inner loop iterates over the columns of the current layer. static void pattern22() { int size = 2 * n - 1; int[][] result = new int[size][size]; for (int layer = 0; layer < n; ++layer) { int num = n - layer; for (int i = layer; i < size - layer; ++i) { for (int j = layer; j < size - layer; ++j) { result[i][j] = num; } } } for (int[] row : result) { for (int col : row) { System.out.print(col + " "); } System.out.println(); } }

In Pattern 22, if someone is coding in c language, there is no min() function so it can be written like this by creating a function: #include int minimum(int a,int b, int c, int d); int main() { int num=4; int n=2*num-1; for(int i=0;i

Edited : Saw you correct it in the next question :-D For pattern 19 , I don't think we should hard code the number of spaces as 8 and then keep on decreasing the number by 2 with each iteration , as it will only work for input n = 5. Rather there should be a general formula : for(int i = n ; i >=1; i--){ for(int j =1; j

For pattern18 if we don't want to hardcode 'E' and use it for other row numbers then we can make small change as char initial = (char) ('A'+ (n-1)); for (int i = 0; i < n; i++) { for (char c = (char) (initial - i); c

problem 22 - For Python: I found below approach most optimised. If u observe (row wise): 1st half and 2nd half is a mirror (ignore middle for a while.) 1st half of a row is a combination of two parts: a - fix part b - decremental part for eg , for n = 6 (considering just 1st half of a row) row1 : 666666 -> all fix , no decremental row2 : 655555 -> 6- decremental , 55555 - fix row3 : 654444 -> 65 - dec , 4444 - fix row4 : 654333 -> 654 - dec , 333 - fix derive the code for dec and fix , then combine the string to generate 1st part of a row , then neglet last character and reverse the result , concatenate both original and reverse to get full row. time difference (n = 500 ) 1. n - min() approach : 256ms 2. above approach : 54 ms

You're answer for question 18 only gets correct answer when n is 5 because you hardcoded E into the for loop. The answer should be: void print18(int n){ for (int i=0;i

39:22 tip for pattern 11: if the sum of every single (row+column) is 'even' then have to print 1 else 0 if((i + j) % 2 === 0) print(1) else print @mehtabmulltani3194

for pattern 18 it will always start from 'E'. Instead, we can code this way better : void pattern18(int n){ char ch = 'A'+n; for(int i=0;i

Pattern 5 my way of doing :- void print5(int n){ int a,b; for(a=1; a=a; b--){ cout
