PROBLEM DESCRIPTION: SOLUTION IN C : #include <math.h> #include <stdio.h> #include <stdlib.h> int reverse(int n) { int s=0,r; while(n>0){ r = n%10; s = s*10 + r; n=n/10;} return s; } int beautifulDays(int i, int j, int k) { int p,num=0; for(int a=i;a<=j;a++) { p=abs(a - reverse(a)); if(p%k==0) num++; } return num; } int main() { int i,j,k,result; scanf("%d %d %d",&i,&j,&k); result = beautifulDays(i, j, k); printf("%d",result); return 0; }
