I have a syntax doubt

At time 15:54, why are we doing " j= j+1 " in else condition. why are not doing in the for loop ?

both are correct
you can do it in loop also

Sir, but we are doing ( j = j+1 ) in the the else condition. if our ’ if condition ’ will be true, then there will be no increment in j.

No
j=j+1 is not in else
it is outside the if condition

check again
