Provide a correct Python 3 solution for this coding contest problem. Your task is to write a program which reads an expression and evaluates it. * The expression consists of numerical values, operators and parentheses, and the ends with '='. * The operators includes +, - , *, / where respectively represents, addition, subtraction, multiplication and division. * Precedence of the operators is based on usual laws. That is one should perform all multiplication and division first, then addition and subtraction. When two operators have the same precedence, they are applied from left to right. * You may assume that there is no division by zero. * All calculation is performed as integers, and after the decimal point should be truncated * Length of the expression will not exceed 100. * -1 × 109 ≤ intermediate results of computation ≤ 109 Input The input is a sequence of datasets. The first line contains an integer n which represents the number of datasets. There will be n lines where each line contains an expression. Output For each datasets, prints the result of calculation. Example Input 2 4-2*3= 4*(8+4+3)= Output -2 60

The well-known Fibonacci sequence F_0, F_1, F_2,… is defined as follows: * F_0 = 0, F_1 = 1. * For each i ≥ 2: F_i = F_{i - 1} + F_{i - 2}. Given an increasing arithmetic sequence of positive integers with n elements: (a, a + d, a + 2⋅ d,…, a + (n - 1)⋅ d). You need to find another increasing arithmetic sequence of positive integers with n elements (b, b + e, b + 2⋅ e,…, b + (n - 1)⋅ e) such that: * 0 < b, e < 2^{64}, * for all 0≤ i < n, the decimal representation of a + i ⋅ d appears as substring in the last 18 digits of the decimal representation of F_{b + i ⋅ e} (if this number has less than 18 digits, then we consider all its digits).

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Note that the only differences between easy and hard versions are the constraints on n and the time limit. You can make hacks only if all versions are solved. Slime is interested in sequences. He defined good positive integer sequences p of length n as follows: * For each k>1 that presents in p, there should be at least one pair of indices i,j, such that 1 ≤ i < j ≤ n, p_i = k - 1 and p_j = k. For the given integer n, the set of all good sequences of length n is s_n. For the fixed integer k and the sequence p, let f_p(k) be the number of times that k appears in p. For each k from 1 to n, Slime wants to know the following value: $$$\left(∑_{p∈ s_n} f_p(k)\right)\ mod\ 998 244 353$$$ Input The first line contains one integer n\ (1≤ n≤ 5000). Output Print n integers, the i-th of them should be equal to \left(∑_{p∈ s_n} f_p(i)\right)\ mod\ 998 244 353.

Provide a correct Python 3 solution for this coding contest problem. We have an integer sequence A of length N, where A_1 = X, A_{i+1} = A_i + D (1 \leq i < N ) holds. Takahashi will take some (possibly all or none) of the elements in this sequence, and Aoki will take all of the others. Let S and T be the sum of the numbers taken by Takahashi and Aoki, respectively. How many possible values of S - T are there? Constraints * -10^8 \leq X, D \leq 10^8 * 1 \leq N \leq 2 \times 10^5 * All values in input are integers. Input Input is given from Standard Input in the following format: N X D Output Print the number of possible values of S - T.
