4-7 statistic a class of complete squares (20 points)

The subject requires the implementation of a function that determines whether any given integer N satisfies the condition: it is a total square number, and at least two digits are the same, such as 144, 676, and so on.

function Interface Definition:

int IsTheNumber ( const int N );

These N are the parameters that the user passed in. If the N condition is met, the function must return 1, otherwise 0 is returned.

Example of a referee test procedure:

#include <stdio.h>#include <math.h>int IsTheNumber ( const int N );int main(){    int n1, n2, i, cnt;    scanf("%d %d", &n1, &n2);    cnt = 0;    for ( i=n1; i<=n2; i++ ) {        if ( IsTheNumber(i) )            cnt++;    }    printf("cnt = %d\n", cnt);    return 0;}/* 你的代码将被嵌在这里 */

Input Sample:

105 500

Sample output:

cnt = 6

int isthenumber (const int N) {int n,m,temp;m=n;n = (int) sqrt (N); if (n*n==m) {int num[10]= {0};<span style= "White-space: Pre "></span>//here the length of NUM should be defined as 10 because the number of digits passed in the integer may be 0~~9 instead of the number of bits passed in. while (m>0) {<span style= "White-space:pre" ></span>//the number on each of the n's, the corresponding array is self-added if there is an array element equal to 2 Description at least 2 digits on the same temp = m%10;for (int i=0; i<=9;i++) {if (temp==i) {num[i]++;if (num[i]==2) {return 1;}}} m/=10;} return 0;} return 0;}
