Please provide a detailed answer with explanations.

In country Macroland, the government borrows at 5% for 1 -year maturity. However, the Central Bank has announced interest rate hikes for the following years, so people expect that the next year the same 1 -year bond will pay 7% and that the interest will rise again to 8% in the year after. Compute and draw the yields curve (for 1-, 2- and 3-years bonds) of the government of Macroland, assuming that there is no risk of default and no inflation and the Central Bank announcements are credible.
