#1

pls correct my code my code fail in sevral testcases and also correct my code
#include
using namespace std;
int main() {
int n;
cin>>n;
int k = n/2+1;
for(int i = 1;i <= k;i++){
for(int space = 3k-4(i-1);space>0;space–){
cout<<" “;
}
for(int j = i;j>0;j–){
cout<<j<<” “;
}
if(i>1){
for(int space = 1;space<3+4*(i-2);space++){
cout<<” ";
}

    for(int j = 1;j<=i;j++){
        cout<<j<<" ";
    }
}

   cout<<endl;


}
 
 for(int i = 1;i <=k;i++){
     for(int s = 1;s<=k+4*(i-1);s++){
         cout<<" ";    
     }
     for(int j = k-i;j >0;j--){
         cout<<j<<" ";
     }
     
     if(i < 3){
         for(int s = 1;s<=n - 4*(i-1) - 1;s++){
        cout<<" ";    
     }
    for(int j = 1;j <= k-i;j++){
         cout<<j<<" ";
     }
     }
     cout<<endl;
 }
return 0;

pls correct my code, my code was giving right output in devc++ but when submitting the hackerblocks it gives wrong output.
#include
using namespace std;
int main(){
int n,v,t;
cin>>n;
int j=n-1;
int space2;
for(int row=1;row<=n;row++){
if(row<=(n/2)+1){
int p=row;
for(int space=1;space<=j;space++){
cout<<" “;
}
j=j-2;
for(int colm=1;colm<=row;colm++){
cout<<p<<” “;
p–;
}
for(int space1=1;space1<=row-1;space1++){
cout<<” “;
}
space2=row-1;
for(int space4=1;space4<=space2-1;space4++){
cout<<” “;
}
for(int no=1;no<=row && row!=1;no++){
cout<<no<<” “;
}
}
else{
for(int space=1;space<=j+2+2;space++){
cout<<” “;
}
j=j+2;
int m=row;
int v=row-j-2;
t=v;
for(int colm=1;colm<=row-j-2;colm++){
cout<<v<<” “;
v–;
}
for(int space3=1;space3<space2;space3++){
cout<<” “;
}
space2–;
}
for(int space5=1;space5<space2;space5++){
cout<<” “;
}
for(int no2=1;no2<=t;no2++ ){
if(t!=1){
cout<<no2<<” ";}
}
cout<<endl;

return 0;
