Explan the meaning of the question

#1

If row number is n (>1), total character is n. First and last character is n-1 and rest are 0.
ones explain the meaning

#2

The logic is simple. When the column position is 0 ie. j==0 and also when j==i (ie. the diagonal element) you will always have to print 1.
In other Cases when j!=0 , you will have to check if i%2==0(ie. even positioned row) . If it is an even positioned row, you will have to print 1, else print 0.

When input is 6:
1 ----> since j==0
11 —> since j==0, j==i
111 —> since j==0, i%2==0, j==i
1001 —> since j==0, i%2!=0, i%2!=0, j==i
11111
100001
and so on.
