This is the value of the arithmetic expression. The operand is a real number greater than or equal to. The operators include +,-, *,/, and (). You only need to open two stacks, one record operator, and one record suffix expression. That is, the

1. Bit vectors represent 0 ~ An integer of N is on a general machine. An integer of the int type has four bytes, a total of 32 bits. We can use different bits in these 32 bits to represent different integers; create an array [100]. Using the concept

Question Description: Xiao Ming always tends to ignore the carry when he does decimal addition with paper and pencer. for example, 15 + 17, Xiao Ming will answer 22, because he ignores the carry from the single digits.5 + 7 = 12, and the digit 1 is

A1 = (A0 + A2)/2-C1, A2 = (A1 + A3)/2-C2 ,... => A1 + A2 = (A0 + A2 + A1 + A3)/2-(C1 + C2) => A1 + A2 = A0 + A3-2 (C1 + C2) similarly, A1 + A2 = A0 + A3-2 (C1 + C2) A1 + A3 = A0 + A4-2 (C1 + C2 + C3) a1 + A4 = A0 + A5-2 (C1 + C2 + C3 + C4 )... a1 +

This question makes the output miserable. The idea of this question is to look at the situation of the n-person. If the n-person takes his previous (n-1) personal things, and the n-person's things, then this event would inevitably happen to f (n-2),

1. Reasons for introducing nullptrThe reason for introducing nullptr is that it should start with NULL. For C and C ++ programmers, NULL is certainly not unfamiliar. However, NULL in C and C ++ is not equivalent. NULL indicates that the pointer does

Why is the time complexity log (n )? First, the idea of tree arrays is itself a tree, so the time complexity of operations is similar to that of the tree. It can also be demonstrated through computation: If the current node is n, the method to reach
