    Với một số nguyên ’n, nhiệm vụ là tìm tổng số các số nguyên tố đầu tiên. & Nbsp; 
      

    Input: N = 4
Output: 17
2, 3, 5, 7 are first 4 prime numbers so their sum is equal to 17

Input: N = 40
Output: 3087

    Approach: 
     

    • Một vài số nguyên tố đầu tiên là: 2, 3, 5, 7, 11, 13, 17, 19, 23,
    • Ví dụ: & nbsp; & nbsp;
    • Tạo một cái sàng sẽ giúp chúng tôi xác định xem số đó có phải là nguyên tố hay không trong thời gian O (1).
    • Chạy một vòng bắt đầu từ 1 cho đến và trừ khi chúng ta tìm thấy n số nguyên tố.

    Thêm tất cả các số nguyên tố và bỏ bê những số không phải là nguyên tố.
     

    C++

    #include <bits/stdc++.h>

    Sau đó, hiển thị tổng số số 1 của N.

    #define MAX 10000

    Dưới đây là việc thực hiện giải pháp trên & NBSP; & NBSP;

    Lưu ý (đối với lập trình cạnh tranh): Trong một vấn đề chứa một số lượng lớn các truy vấn, một vectơ có thể được sử dụng để lưu trữ tất cả các số nguyên tố trong phạm vi 10^8, điều này sẽ có thêm không gian O (n). Chúng ta cũng có thể sử dụng mảng tiền tố để lưu trữ tổng số n số đầu tiên trong phạm vi 10^8. & nbsp; In a
    problem which contains a large number of queries, a vector can be used to store all the prime numbers in the range of 10^8, this will take extra O(N) space. We can also use prefix array to store the sum of first N prime numbers in the range of 10^8.
