Today I came accross an awesome interview question for programmers.
Problem
Given this psuedo C like code;
if "operation" printf("Hello"); else printf("World");
What “condition” would cause it to output “HelloWorld”?
C Solution
if (0 == printf("Hello")) printf("Hello"); else printf("World");
C# Solution
if ((new string[] { "Hello" }).All<string>(delegate(string n) { Console.Write(n); return false; })) { Console.Write("Hello"); } else { Console.Write("World"); }
JAVA Solution
Graciously from Jack Dunham (the Java man);
if (new Object() {@Override public boolean equals(Object foo) { System.out.print("hello ");return false;}} .equals("hello ")) { System.out.print("hello "); } else { System.out.print("World"); }
