自同构数
给定一个数 N，任务是检查这个数是否是自同构数。当且仅当一个数的平方与数本身的位数相同时，这个数称为自同构数。 例:
Input : N = 76
Output : Automorphic
Explanation: As 76*76 = 5776
Input : N = 25
Output : Automorphic
As 25*25 = 625
Input : N = 7
Output : Not Automorphic
As 7*7 = 49
1\. Store the square of given number.
2\. Loop until N becomes 0 as we have to match
all digits with its square.
i) Check if (n%10 == sq%10) i.e. last digit
of number = last digit of square or not
a) if not equal, return false.
ii) Otherwise continue i.e. reduce number and
square i.e. n = n/10 and sq = sq/10;
3- Return true if all digits matched.
C++
// C++ program to check if a number is Authomorphic
#include <iostream>
using namespace std;
// Function to check Automorphic number
bool isAutomorphic(int N)
{
// Store the square
int sq = N * N;
// Start Comparing digits
while (N > 0) {
// Return false, if any digit of N doesn't
// match with its square's digits from last
if (N % 10 != sq % 10)
return false;
// Reduce N and square
N /= 10;
sq /= 10;
}
return true;
}
// Driver code
int main()
{
int N = 5;
isAutomorphic(N) ? cout << "Automorphic"
: cout << "Not Automorphic";
return 0;
