Solve any square or hollow pattern in Java

[@Movies_elitee]

At 14:18 why it can't be j==1 since you showed i==1,j==1,j==i

[@PuspenduBiswas-jn2mq]

@SimplyCoding In this video at 7:41 min you have mentioned that to find middle row and column we use the formula n/2+1 but the formula should be (n+1)/2 for odd number and n/2 for even number.

Mam please can you also make a DSA playlist🙏🙏...ur teaching way is supebbbb... and simplest...💓🔥

Thanks, yes we have already done a few DSA videos and we will create a playlist for same. Will also finish the remaining videos as well.

In hollow hill pattern, in second triangle isn't that a diagonal and we can use the formula (i+j==n+1), then why is the formula j==1?

[@tsionasmare8243]

i also agree with u

[@hrushikeshmandekar6572]

The reasons behind this is that concept i+j will not work here, just forgot that concept, in easy way I will tell you that, in second triangle see from where j is starting in for loop, its j = 1, so j is going to start always from 1 as we move downwards, means j = 1 is the first element for second triangle at each row, so we can say that j = 1 is making the border for second triangle, so that is why we are checking the first element of 2nd triangle every time in if statement that is j == 1 so that whenever it will come, we will create a star, so likewise the border is created for second triangle. In third triangle look what is making border, that's the last element that is when j == i, so that is why we have taken j == i in if statement of third for loop.

[@nishanthulwan1478]

Just one question if you can answer on the last question when you are printing Diagonal why are you doing j == n? it should be i + j == n + 1 right ??

[@nishanthulwan1478]

this is for hollow decreasing traingle

hollow decreasing triangle was incorrect , it should be package Loops_in_Java; public class right_downward_triangle_hollow { public static void main(String[] args) { int n = 5; for (int i = 1; i

[@muhmmadsaleh3145]

Hill pattern code is not giving the desired pattern and the diamond pattern also plaease correct it

Can you send your code at [e-mail] so that we can help correct it?

Hollow decreasing triangle is it crt or we can write it a if(i=1||j=1||i+j/n+1) I think it is crt code plz reply

[@BoobieMistake]

No, the if condition should be "if (i==1 || j==1 || i+j==(n+1))"

[@Akl_Badi_Ya_Bhains]

Hi, thank you for such an exceptional video. I have one doubt though. While taking the if-condition for 2nd triangle of Hollow Hill Pattern (at 15:14), we are using the condition "if(i == n || j == 1)." Why are we using j == 1 when I think it should have been j == i. I know you r correct and I am wrong, but I am unable to get it, can u please explain.

[@balapaudel]

j==1 helps us print the first star in each row. remember we print one line at a time. j prints stars in each line always starting from 1. And we need the 1st star in each line so j==1. j==i doesn't work because i is responsible for rows. again remember we print one line at a time. for first row j will print a star because i==1 at first row but when we need to print second row the value of i becomes 2 but we need 1st star of each row. So this won't work.

[@chandrikaobulasetty6944]

Take a example to understand it. Lets say you have pattern of 5 stars so middle row/col is 5/2 + 1 which is 3. If it is pattern of 7 stars, then the middle row is 7/2 + 1 which is 4 and so on.

Middle row = n/2+1 can anybody elaborate ?

[@SimplyCoding]

Suppose n is 7. Since n is int, when we do n/2, it will give 3 as decimal part will be truncated. However middle row is 4. so we add 1 to it.

[@MR-gv4bv]

@@SimplyCoding so if n is 8 is it just n/2 ? not n/2+1 ?

[@MR-gv4bv]

@@SimplyCoding and what about Left diagonal ? i+j == n+1 ? what 1 for ? why it really different from Major diagonal ?

[@SimplyCoding]

It case of even nos. like 8, technically there is no middle row, it can be fourth or fifth or both. if your exam question asks you to handle it, I am sure you can work out the middle rows since you know the formula now.
