If we are to find frequency of only one number let us say 35 in infinite
coming numbers , do xor operation with coming numbers If the result is 0
increment the value of temp variable by 1 if not scan next input until all
numbers are over.

Take an array a[1000]input first 1000 values from the stream in it..
Here we are representing a unit time with help of space because 1000
elements in a stream will always come in constant time
So just count the occurrence of a given number in that array... then divide
the count with 1000
