JavaScript Program to find kth element from two sorted arrays
function kth ( arr1 , arr2 , m , n , k ) { var sorted1 = Array ( m + n ) . fill ( 0 ) ; var i = 0 , j = 0 , d = 0 ; while ( i < m && j < n ) { if ( arr1 [ i ] < arr2 [ j ] ) sorted1 [ d ++ ] = arr1 [ i ++ ] ; else sorted1 [ d ++ ] = arr2 [ j ++ ] ; } while ( i < m ) sorted1 [ d ++ ] = arr1 [ i ++ ] ; while ( j < n ) sorted1 [ d ++ ] = arr2 [ j ++ ] ; return sorted1 [ k - 1 ] ; }
