Find 2 second largest Array element | arrays Interview question

To find the second largest element in an array, we can follow these steps:

1. Initialize two variables, 'first_max' and 'second_max,' to negative infinity.
2. Iterate through the array.
3. For each element, if it is greater than 'first_max,' update 'second_max' to be 'first_max' and 'first_max' to be the current element.
4. If the element is greater than 'second_max' but not equal to 'first_max,' update 'second_max' to be the current element.
5. After iterating through the array, 'second_max' will hold the second largest element.

This algorithm ensures that the second largest element is found without sorting the array and with a single pass through the data.
