One test case failed

#1

Can you please tell me what is wrong in the code as one test case is failing
#include
#include
using namespace std;

void print2darray(int a[100][100],int n,int m){
int i,j;
for(i=0;i<n;i++){
for(j=0;j<m;j++){
cout<<a[i][j]<<’ ';
}
cout<<endl;
}
}

int main(){
int n,m,num,sr,sc,er,ec,i,j,k,l,row,col;
cin>>n>>m;

int a[100][100] = {};
for(i=0;i<n;i++){
	for(j=0;j<m;j++){
		cin>>num;
		a[i][j] = num;
	}
}

sr = 0;
sc = 0;
er = n-1;
ec = m-1;

while(sr<=sc && sc<=ec){

	for(row=sr;row<=er;row++){
		cout<<a[row][sc]<<", ";
	}
	sc++;

	for(col=sc;col<=ec;col++){
		cout<<a[er][col]<<", ";
	}
	er--;

	if(sc<ec){

		for(row=er;row>=sr;row--){
			cout<<a[row][ec]<<", ";
		}
		ec--;
	}

	if(sr<er){

		for(col=ec;col>=sc;col--){
			cout<<a[sr][col]<<", ";
		}
		sr++;
	}
}
cout<<"END";
return 0;

}

#2

it should be sc<=ec

simillarly

this should also be sr<=er

#3

But wouldn’t this print the values twice if of the same row??

#4

I don’t think so
have you test the code after changes i told you

kindly share the link of code after changes
i will check it

#5

it still shows that particular test case failed
#include
#include
using namespace std;

void print2darray(int a[100][100],int n,int m){
int i,j;
for(i=0;i<n;i++){
for(j=0;j<m;j++){
cout<<a[i][j]<<’ ';
}
cout<<endl;
}
}

int main(){
int n,m,num,sr,sc,er,ec,i,j,k,l,row,col;
cin>>n>>m;

if(n>=1 && n<=10 && m>=1 && m<=10){

	int a[100][100] = {};
	for(i=0;i<n;i++){
		for(j=0;j<m;j++){
			cin>>num;
			a[i][j] = num;
		}
	}

	sr = 0;
	sc = 0;
	er = n-1;
	ec = m-1;

	while(sr<=sc && sc<=ec){

		for(row=sr;row<=er;row++){
			cout<<a[row][sc]<<", ";
		}
		sc++;

		for(col=sc;col<=ec;col++){
			cout<<a[er][col]<<", ";
		}
		er--;

		if(sc<=ec){

			for(row=er;row>=sr;row--){
				cout<<a[row][ec]<<", ";
			}
			ec--;
		}

		if(sr<=er){

			for(col=ec;col>=sc;col--){
				cout<<a[sr][col]<<", ";
			}
			sr++;
		}
	}
	cout<<"END";
}
else{
	
}
return 0;

}
