prev  |  next  |  chance

Given a string, switch every "x" with the letter following it. You are guaranteed that "x" is not the last letter, and that there are no consecutive "x"s. There might be multiple occurrences of x in the String.

switchXwithNext("axb") → "abx"
switchXwithNext("xabc") → "axbc"
switchXwithNext("axbxcxd") → "abxcxdx"

...Save, Compile, Run (ctrl-enter)

public String switchXwithNext(String str) { }
