I have done exactly same thing but my code is not passing all the test cases o hacker block, may ik my error

#1

#include
using namespace std;
int main() {
int m,n;
cin>>m>>n;
int a[m][n];
for(int i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
cin>>a[i][j];
}
}
int sr=0;
int sc=0;
int er=m-1;
int ec=n-1;
while(sr<=er and sc<=ec)
{
for(int i= sc;i<=ec;i++)
cout<<a[sr][i]<<" “;
sr++;
for(int i= sr;i<=er;i++)
cout<<a[i][ec]<<” “;
ec–;
if(er>sr)
{for(int i= ec;i>=sc;i–)
cout<<a[er][i]<<” “;
er–;}
if(ec>sc)
{for(int i= er;i>=sr;i–)
cout<<a[i][sc]<<” ";
sc++;
}

}

return 0;

}

hello @ganesh2512

use >= in place of > in above if statements

#3

but in lecture, bhaiya told to use >. >= is covered in while loop

#4

if u will use > , then some row /column might remain unprinted

#5

yes that worked on hacker block, but I in video it was taught different

#6

also see second soln in this link

#7

…

which link ?
…
…

#8
#9

yeah whats the issue?

#10

here also in soln 2, it says <, not<=

#11

…

thier m is not pointing to last column , it is pointing next index of last column thats why they are using < and not <=

#12

are you getting my doubt, in video ,bhaiya used >,not >=,same at gfg

#13

…

are u reading my replies? gfg code is not same as urs.
dry run on small test cases and spot the difference.

#14

got it, thankyou, your replies were not visible here,just saw them at mail
