When value of i=2 j=1 is a,b,\0,\0 then in next step when i=3 j=2 how do we have value of output array a,c,\0,\0

@pranjuldwivedi120568 when you have ab there will be two conditions next time i+1,j+1 and i+1,j so in i+1,j j remains at 1 so ab becomes ac
for better understanding remove b
when string is a you have to options include b or not
if include it becomes ab else a
now for a there are two options include c or not
so if include it becomes ac
