Write the function that takes one parameter, a non-empty String str (such as "Code") and returns a String in the form "CCoCodCode". Notice that this includes the first character of the original String, followed by the first twocharacters, and so on until the whole String is used.

Here are some examples:

stringSplosion("Code") returns "CCoCodCode"

stringSplosion("abc") returns "aababc"

stringSplosion("x") returns "x"

I believe the for condition is ( int i = 0 ; i < len ; i++), but I don't know how to continue.

Please use a for loop and if you can explain cause I'm a beginner
