Adding missing lines in file

Dear all,

I have a file with two columns - the first column is increasing every 50, the second column is just count (e.g. 5). However, when count is zero, no line is present.

Sample:

Code:
1950    7
2000    14
2050    7
2100    13
2150    10
2200    9
2250    7
2300    8
2350    7
2400    4
2450    5
...
6550    1
6600    2
7050    1
7150    1

How can I change the file so as to include lines with zero count? e.g. in the previous file to put between the bold numbers

Code:
6600 2
6650 0
6700 0
6750 0
6800 0
6850 0
6900 0
6950 0
7000  0
7050 1
7100 0
7150 1

How can I do it?

Thanks
