• Back in goAgain("today", 1)
• Finished the recursive call, got back "odayay"
• Computes "today" + "odayay", which is "todayodayay"
• Stops and returns "todayodayay"

Resulting call stack

g("ay", 3)  returns "ay"
g("oday", 2)     "oday" + "ay"  returns "odayay"
g("today", 1)    "today" + "odayay"  returns "todayodayay"
