### Intuition
The problem is to determine how many ways an array can be split such that the sum of elements in the left part is greater than or equal to the sum of elements in the right part. The main insight is to compute the total sum of the array once, then track the running sum while iterating to evaluate conditions at each potential split point.

---

### Approach
1. **Initial Setup**: Compute the total sum of the array.
2. **Iterate Through the Array**:
   - Maintain a running sum (`curSum`) of the left part.
   - At each split point \( i \), check if `curSum` is greater than or equal to the sum of the right part (`sum - curSum`).
   - If the condition holds, increment the count (`count`).
3. **Return Result**: After processing all valid split points, return the count.

---

### Complexity
- **Time Complexity**: 
  - The loop iterating through the array runs in \( O(n) \), where \( n \) is the size of the array.
  - Computing the total sum initially also takes \( O(n) \).
  - Hence, the overall time complexity is \( O(n) \).

- **Space Complexity**:
  - The algorithm uses \( O(1) \) additional space since the computation only requires a few variables.

To make the code for Java, Python, Go, and other languages appear in different tabs of a single code box, you can use Markdown with tabbed code syntax supported by tools like GitHub or other Markdown renderers that support tabbed views. Below is an example of how to format it:

### Tabbed Code Example


### Implementation

Here’s the updated tabbed code snippet including implementations in C, C++, Python3, and the original languages:

```java [Java]
class Solution {
    public int waysToSplitArray(int[] nums) {
        if (nums.length < 2) return 0;

        long totalSum = 0, leftSum = 0;
        for (int num : nums) {
            totalSum += num;
        }

        int count = 0;
        for (int i = 0; i < nums.length - 1; i++) {
            leftSum += nums[i];
            if (leftSum >= (totalSum - leftSum)) {
                count++;
            }
        }
        return count;
    }
}
```

```python [Python3]
class Solution:
    def waysToSplitArray(self, nums: List[int]) -> int:
        total_sum = sum(nums)
        left_sum = 0
        count = 0
        
        for i in range(len(nums) - 1):
            left_sum += nums[i]
            if left_sum >= (total_sum - left_sum):
                count += 1
        
        return count
```

```cpp [C++]
class Solution {
public:
    int waysToSplitArray(vector<int>& nums) {
        long long totalSum = 0, leftSum = 0;
        int count = 0;
        
        for (int num : nums) {
            totalSum += num;
        }
        
        for (int i = 0; i < nums.size() - 1; i++) {
            leftSum += nums[i];
            if (leftSum >= (totalSum - leftSum)) {
                count++;
            }
        }
        
        return count;
    }
};
```

```c [C]
#include <stdio.h>

int waysToSplitArray(int* nums, int numsSize) {
    long long totalSum = 0, leftSum = 0;
    int count = 0;

    // Calculate total sum
    for (int i = 0; i < numsSize; i++) {
        totalSum += nums[i];
    }

    // Iterate to find valid splits
    for (int i = 0; i < numsSize - 1; i++) {
        leftSum += nums[i];
        if (leftSum >= (totalSum - leftSum)) {
            count++;
        }
    }

    return count;
}
```

```javascript [JavaScript]
/**
 * @param {number[]} nums
 * @return {number}
 */
var waysToSplitArray = function(nums) {
    let totalSum = nums.reduce((sum, num) => sum + num, 0);
    let leftSum = 0;
    let count = 0;
    
    for (let i = 0; i < nums.length - 1; i++) {
        leftSum += nums[i];
        if (leftSum >= (totalSum - leftSum)) {
            count++;
        }
    }
    
    return count;
};
```

```go [Go]
func waysToSplitArray(nums []int) int {
    totalSum := 0
    leftSum := 0
    count := 0
    
    for _, num := range nums {
        totalSum += num
    }
    
    for i := 0; i < len(nums)-1; i++ {
        leftSum += nums[i]
        if leftSum >= (totalSum - leftSum) {
            count++
        }
    }
    
    return count
}
```
