Easiest Solution in C
Code
# Code
```c []
bool isBalanced(char* num) {
    int oddSum = 0, evenSum = 0, len = strlen(num);
    for (int i = 0; i < len; i++) {
        if (i % 2 == 0)
            evenSum += (num[i] - '0');
        else
            oddSum += (num[i] - '0');
    }
    return oddSum == evenSum;
}
