Vorzeichenbehafteter Ganzzahlüberlauf: 998765432 * 10 kann nicht im Typ „int“ dargestellt werden ... Was mache ich hier? ⇐ C++

[Anonymous]

Code:

Code: Select all

class Solution {
public:
bool isPalindrome(int x) {
int out = 0;
int normal = x;
while(normal > 0){
out *= 10;
out += normal % 10;
normal /= 10;
}

if(out == x){
return true;
} else {
return false;
}
}
};

Fehler:

Code: Select all
