I tried many times to understand this program but I am unable to get it. How it is printing the pattern?

hello @bhavish_rohilla

in this program all we have used is if while loop and observation.

observations
a) total number of entries in any row is equal to the row number.
for example if row no is 1 then number of entries in this row will be 1.
if row no is 5 then number of entries in this row will be 5.

b) if row is even then first and last entry is 1 and rest is 0
c) if row is odd then all entries of this row is 1.

so we are running a loop from row no 1 to row no n
and printing the entries of that rows .
