signed integer overflow: 9 * 1000000000 cannot be represented in type 'int' (solution.cpp) code example

Example: runtime error: signed integer overflow: 964632435 * 10 cannot be represented in type 'int'

while (x != 0) {
        int pop = x % 10;
        x /= 10;
        if (rev > INT_MAX/10 || (rev == INT_MAX / 10 && pop > 7)) return 0;
        if (rev < INT_MIN/10 || (rev == INT_MIN / 10 && pop < -8)) return 0;
        rev = rev * 10 + pop;
    }
