# Operations in a Sorted Array

### Inserting in a Sorted Array :

To insert a new element in a sorted array, keep shifting the rightmost elements to the right by 1 until the element to be inserted is not greater than the element to be shifted.

```c
void insertInSorted(int a[], int n, int x) {

    int i = n-1; // Shift from right
    
    // Shifting elements to the right
    while (i >= 0 && a[i] > x) {
        a[i+1] = a[i];
        i--;
    }
    
    // Inserting element in proper position
    a[i+1] = x;
    
}
```

### Checking if an Array is Sorted :

To check if an array is sorted, compare the ith element with (i+1)th element and check if ith element is greater than (i+1)th element. If it is so, this means that the array is not sorted.

```c
int isSorted(int a[], int n) {

    // Iterate till length - 1
    for(int i = 0; i < n-1; i++) {
        // Case for unsorted array
        if (a[i] > a[i+1]) {
            return 0;
        }
    }
    return 1;
    
}
```

### Rearranging an Array

In this operation, all the negative numbers in the array are moved to the left side of the array while all the positive numbers are moved to the right side of the array.

```c
void rearrange(int a[], int n) {
    
    int j = 0;
    for (int i = 0; i < n; i++) {
        // If negative number => Swap a[i] and a[j]
        if (a[i] < 0) {
            if (i != j) {
                swap(&a[i], &a[j]);
            }
            j++;
        }
    }
    
}
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://nitinranganath.gitbook.io/data-structures/arrays/operations-in-a-sorted-array.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
