检查给定数字的所有旋转是否大于或等于给定数字

给定整数x ，任务是查找元素上的每个k周期移位是否产生大于或等于相同元素的数字。
整数x的k循环移位是删除x的最后k个数字并将其插入其开头的函数。
例如，对于k ＝ 1 ，k循环移位123为312 ，对于k ＝ 2 ，k循环移位为231 。如果满足给定条件，则打印“是”，否则打印“否” 。
例子：

Input: x = 123 
Output : Yes 
The k-cyclic shifts of 123 are 312 for k=1 and 231 for k=2. 
Both 312 and 231 are greater than 123.
Input: 2214 
Output: No 
The k-cyclic shift of 2214 when k=2 is 1422 which is smaller than 2214 
 

方法：只需找到该数字的所有可能的k个循环移位，然后检查所有数字是否大于给定数字。
下面是上述方法的实现：

C++

// CPP implementation of the approach
#include
using namespace std;
 
void CheckKCycles(int n, string s)
{
    bool ff = true;
    int x = 0;
    for (int i = 1; i < n; i++)
    {
 
        // Splitting the number at index i
        // and adding to the front
        x = (s.substr(i) + s.substr(0, i)).length();
 
        // Checking if the value is greater than
        // or equal to the given value
        if (x >= s.length())
        {
            continue;
        }
        ff = false;
        break;
    }
    if (ff)
    {
        cout << ("Yes");
    }
    else
    {
        cout << ("No");
    }
}
 
// Driver code
int main()
{
    int n = 3;
    string s = "123";
    CheckKCycles(n, s);
    return 0;
