$ Str = array (
"Helloworld ",
"Howareyou ",
"Cpufrequency ",
"Windows7ready ",
"Newedition2 ",
"Downloadurllist ",
"Heisasuperhero ",

// Your solution

/*
After adding spaces correctly, it should be:
"Helloworld" = "hello world"
"Howareyou" = "how are you"
"Cpufrequency" = "cpu frequency"
"Windows7ready" = "windows 7 ready"
"Newedition2" = "new edition 2"
"Downloadurllist" = "download url list"
"Heisasuperhero" = "he is a super hero"
