Dry run of Pattern problem

#1

I’m unable to understand the Dry run for the pattern problem in which we have to print 1 in odd rows and first and last number will be printed 1 and zeros in middle for even rows

hello @shazanahmed1
u r approach is correct , if row number is odd then u need to print all 1, otherwise if even then u need to print first and last column as 1 and remaining all should be 0.

for example let say n=5
odd…row1 -> 1
even row2 -> 1 1
odd row3 -> 1 1 1
even row4 -> 1 0 0 1
odd row5 -> 1 1 1 1 1

I understood how pattern is getting printed for the odd and even numbered rows , but I’m unbale to understand how the Row value and column values get updated in the loop execution process.

for row = 1 to N
      if row is odd
           print 1 row times    
       else 
         print 1 and then print 0 row-2 times and then again print 1

this is how updation is happening
