Arrays-Spiral Print Anticlockwise

#1

can’t understand how to do…

#2

In this question, you can maintain 4 variables as top, bottom left and right, initialise them as ,
int top=0,bottom=M-1,left=0,right=N-1;
and then take a direction variable as initialised to 0,
Then maintain the while condition as ,
while(top<=bottom && left<=right)
and then check if direction is 0, then print the array from top to bottom… and while doing that increment the direction variable… for eg,
for(int i=top;i<=bottom;i++)
{
cout<<ar[i][left]<<","<<" ";
}
left++;
direction=1;

Similarly, you need to follow up the approach for all different directions…

#3

when to reset the direction variable

#4

@yuktimutreja01 please tell

#5

Whenever you are printing one side of matrix, you are required to update the direction variable… as I have told you in the code snippet above…
