The method printPopSong prints the words to a song. It initializes the value of the variable i equal to $5$ and then checks if i is greater than $0.$ Since $5$ is greater than $0,$ the body of the loop executes. Before the condition is checked again, i is decreased by $1.$ When the value in i is equal to $0$ the loop stops executing.

Can you make the loop count by $2$s backwards? It should print out $531?$ Remember to change all $3$ parts of the for loop.
