摘要： === 1. and運算 ===( & ) and運算通常用于二進制取位操作，例如一個數 and 1的結果就是取二進制的最末位。這可以用來判斷一個整數的奇偶，二進制的最末位為0表示該數為偶數，最末位為1表示該數為奇數. 相同位的兩個數字都為1，則為1；若有一個不為1，則為0。 00111 11100 （&或者and） ---------------- 00100=== 2. or運算 ===( | ) or運算通常用于二進制特定位上的無條件賦值，例如一個數or 1的結果就是把二進制最末位強行變成1。如果需要把二進制最末位變成0，對這個數or 1之后再減一就可以了，其實際意義就是 閱讀全文

摘要： DescriptionPalindromes are numbers that read the same forwards as backwards. The number 12321 is a typical palindrome.Given a number base B (2 <= B <= 20 base 10), print all the integers N (1 <= N <= 300 base 10) such that the square of N is palindromic when expressed in base B; also pri 閱讀全文

摘要： DescriptionConsider the number triangle shown below. Write a program that calculates the highest sumof numbers that can be passed on a route that starts at the top and ends somewhere on the base. Each step can go either diagonally down to the left or diagonally down to the right. 7 3... 閱讀全文
