[algogeeks] print spiral
given a matrix m*n print elements in spiral
eg
1 2
3 4
5 6 = 1,2,4,6,5,3
1
2
3 =1,2,3
i wrote following code but for the case 2 printing 1,2,3,2
I wish to avoid keeping a counter of how many elements have been print so
far...
void spiral(int a[], int m, int n) {
while ( (rs(m+1)/2) (cs (n+1)/2)) {
int r=rs;
int c=cs;
for (int j=c;jn-c-1;j++) printf(%d ,a[r][j]);
for (int i=r;im-r-1;i++) printf(%d ,a[i][n-c-1]);
for (int j=n-c-1;jc;j--) printf(%d ,a[m-r-1][j]);
for (int i=m-r-1;ir;i--) printf(%d ,a[i][c]);;
rs++;cs++;
}
}

Re: [algogeeks] print spiral
check no. of elements printed in all inner for loop also
for (int j=c;jn-c-1 cntm*n;j++) {printf(%d ,a[r][j]); cnt++;}
for (int i=r;im-r-1 cntm*n;i++) {printf(%d ,a[i][n-c-1]); cnt++}
for (int j=n-c-1 cntm*n;jc;j--) {printf(%d ,a[m-r-1][j]); cnt++}
for (int i=m-r-1 cntm*n;ir;i--) {printf(%d ,a[i][c]); cnt++}

Re: [algogeeks] print spiral
yes, using count i solved this, but IMHO, this should be done without this
count somehow..
