等式(a + b)<= n中的’a’的打印值可被x整除

给定三个数字b，x，n。任务是找到等式(a + b)<= n中的’a’值，以使a + b被x整除。如果没有这样的值，则打印-1。

例子：

Input: b = 10, x = 6, n = 40
Output: 2 8 14 20 26

Input: b = 10, x = 1, n = 10
Output: -1

方法：人们可以找到最小的可能值(b / x + 1)* x – b。然后我们将答案增加x，直到不大于n。这里(b / x +1)* x是被x整除的最小可能值。

下面是上述方法的实现：

C++

// CPP program to Find values of a, in equation
// (a+b)<=n and a+b is divisible by x.
#include 
using namespace std;
  
// function to Find values of a, in equation
// (a+b)<=n and a+b is divisible by x.
void PossibleValues(int b, int x, int n)
{
    // least possible which is divisible by x
    int leastdivisible = (b / x + 1) * x;
  
    int flag = 1;
  
    // run a loop to get required answer
    while (leastdivisible <= n) {
  
        if (leastdivisible - b >= 1) {
            cout << leastdivisible - b << " ";
  
            // increase value by x
            leastdivisible += x;
  
            // answer is possible
            flag = 0;
        }
        else
            break;
    }
  
    if (flag)
        cout << -1;
}
  
// Driver code
int main()
{
    int b = 10, x = 6, n = 40;
  
    // function call
    PossibleValues(b, x, n);
  
    return 0;
}
