where can I get these kind of exercises to solve?

Question

Recently I did a Java programming exercise successfully which was sent by a recruiting firm, The problem statement goes like this 'There are two text files FI(records abt files and directory information) and FS(containing blocks of data) which represent a file Index and file System respectively and I was supposed to write a static read method in a class which will read the file from the FS depending upon the path string provided using FI' My question is where can I get these kind of exercises to solve, the complexity should be above average to tough.

Answer 1

Start here:

• Project Euler
• Programming Praxis
• CodeKata

Warning! These can become addictive causing you to anger a spouse and/or boss by spending too much time doing "just one more." (I'm guilty of angering both.)

I know they're not the kind that appear in interviews, but maybe you're interested as well.
