Some Phone Interview Programming Questions

I sometimes try phone interviews with companies. It is both a refreshment for me and a fun way to challenge yourself. These questions are easy ones though, but can be noted.

• Find duplicate element in an N array.
• [1,2,3,4,5,4] > 4
• Given earth and 1 billion star location, find 100 closest stars to earth
• locations in 3d
• Write parseInt function in Java.
• 123 > 123
• 123.00 > 123
• 123ab > Exception
• 123.ab > Exception
• 123.50 > Exception (or rounding)
• 12323123123131231231312312312 > Exception
