1) An array A is of size N. Write a java method that jumbles all values in the array.
All possible permutations must be possible and chances for each possible
permutation must be equal. For example, size of array A is 3.A[0]=x,A[1]=y,A[2]=z.
Possible permutations are 3!.After jumbling elements, there would be equal chances
for each of xyz, yxz , ....to be in the array elements.


2) 50,000 html files are in a folder on a windows machine.Among them,content of some files
(not the file names)contain the sentence "Welcome to java!".Write a java program
to count the no of such files.

We're not going to write it for you, so what is it you are stuck on?

Post your code and ask specific questions about it and we can probably help you get it right.

The biggest difference between time and space is that you can't reuse time...
