Therefore, 0xcafebabe is a negative number, which must be expanded first when adding, so that it becomes 0 xffffffffcafebabe.

value, the lower the value, and the higher the value. For example, if 130 is converted to binary 1000,001 0, a total of 8 bits are required. one byte cannot be expressed. Therefore, two bytes are required. The first byte represents the last 7 bits, in addition, the highest position 1 indicates that there is a byte next to it, so it is (1) 0000010, the second

>=1; RET + = N;} return ret + 1 ;} [Solution 2 of Question 2] N! Contains the number of prime factor 2, which is equal to the number of 1 in the binary representation of N minus n. We can also solve this problem through this rule. The following is an example of this rule. Suppose n = 11011, then n! The number of prime factor 2 is n/2 + N/4 + N/
