    <p>here is pseudo code on algorithm to find median of two array</p> <pre><code>T WO -A RRAY-M EDIAN (X, Y ) n ← length[X] £ n also equals length[Y ] median ← F IND -M EDIAN (X, Y, n, 1, n) if median = NOT- FOUND then median ← F IND -M EDIAN (Y, X, n, 1, n) return median F IND -M EDIAN ( A, B, n, low, high) if low &gt; high then return NOT- FOUND else k ← (low + high)/2 if k = n and A[n] ≤ B[1] then return A[n] elseif k &lt; n and B[n − k] ≤ A[k] ≤ B[n − k + 1] then return A[k] elseif A[k] &gt; B[n − k + 1] then return F IND -M EDIAN ( A, B, n, low, k − 1) else return F IND -M EDIAN ( A, B, n, k + 1, high) </code></pre> <p>it is from introduction of algorithms MIT </p> <p>and here is my code please if something is wrong in my code tell me </p> <pre><code> public class findmedian{ public static int find(int []x,int []y){ int median; int n=x.length; median=Median( x, y, n,0, n); if ( median&lt;-100000){ Median(y,x, n,1, n); } return median; } public static void main(String[]args){ int x[]=new int[]{3,5,7,8,5,9,10}; int y[]=new int[]{12,4,8,9,6,7,10}; find(x,y); } public static int Median(int []a,int []b,int n,int low,int high) { if ( low&gt;high) return -1 ; int k=(low+high)/2; if (k==n &amp;&amp; a[n]&lt;=b[1]) return a[n]; else if ( k&lt;n &amp;&amp; b[n-k]&lt;=a[k] &amp;&amp; b[n-k]&lt;=b[n-k+1]) return a[k]; else if ( a[k]&gt; b[n-k-1]) return Median( a,b,n,low,k-1); return Median(a,b,n,k+1,high); } } </code></pre> <p>after compile it does not return anything please help</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
