Tcl Programming using string

I want to write a TCL program for a given input string "Hello I Am Fine" , whose output must be: "Fine Am I Hello"

Also Want to know, how to find the last element within a list of elements? Eg: [list 10 20 30 40 50 60 70 80 90 100] -- So from this list i want to use the last element.

Thanks.

If you need the last element of a list, you can access it with

lindex $list end

If you want to know the index of the last element, use

expr {[llength $list] - 1}

If you want to reverse a list, use

set newList [lreverse $list]

Simple as that.

And for the the Input/Output thing, I suggest first split it into a list, then reverse it, and join the result again. I leave it to you as exercise.
