Suppose there are 5 types of coins: 50-cent, 25-cent, 10-cent, 5-cent, and 1-cent. we want to make changes with these coins for a given amount of money. For example, if we have 11 cents, then we can make changes with one 10-cent coin and one 1-cent coin, two 5-cent coins and one 1-cent coin, one 5-cent coin and six 1-cent coins, or eleven 1-cent coins. so there are four ways of making changes for 11 cents with the above coins. note that we count that there is one way of making change for ze

Let's talk about: This question is similar to the eight queens question. A square board with N * n and n Analysis: In the eight queens issue, we considered the entire board into eight rows, with one piece inserted in each row. Therefore, the solution for this problem is similar, with a row inserted. However, what is different from the eight queens issue is that multiple pawns may be inserted or no pawns may exist on the board. Therefore, in recursive functions, not only the information of the
