pseudo algo:
=>array idx[0...k-1] .... indicates the current pointer position in the ith
stream(initialized to 0).
=>heap tree of size k where each node stores value of the data and value of
stream which the node belongs to.
do{
for all i = 0:k-1
=>insert idx[i] value of ith stream to the heap
=>take the root element of the heap and put it in the output stream.
=>idx[m]++ where m is the stream value stored at the root.
} while(true);
