Hostel Visit output doubt

[tushargupta.tg2609 (Tushar Gupta)]

i m not able to understand why third output is 98 rather than 128

[Anubhav-Aron-1353657628083250 (Anubhav Aron)]

At the third output:
Hostel Built are

1. Coordinate : 10 ,10 Distance :200
2. Coordinate : 9 ,9 Distance :162
3. Coordinate : -8 -8 , Distance : 128
4. Coordinate : 7 7 Distance : 98
5. Coordinate : 6 ,6 Distance :72
6. Coordinate : 5, 5 Distance :50
   So,
   you need to print the kth nearest(smallest) distance
   Here k=3
   so third smallest distance = 98
   As 50<72<98<128<168<200
   Hit like if u get it
