Summary

In FundFlowController the function _sortIndexesDescending sorts an array of values in descending order and returns an array of the original indices corresponding to the sorted values. It employs a bubble sort algorithm, which is simple but inefficient for large arrays due to its quadratic time complexity.

Impact

1. Inefficient Sorting (Bubble Sort):
   Bubble sort has O(n²) complexity, making it slow and gas-inefficient for large arrays.
   This can lead to high gas costs and potential out-of-gas errors during execution, especially with larger datasets.

2. Performance Bottleneck:
   The algorithm's inefficiency limits contract scalability, reducing performance as array sizes grow.

Recommendations

Replace the bubble sort with a more efficient algorithm like QuickSort or MergeSort, both of which have average time complexities of O(n log n). This will significantly reduce execution time and gas consumption for large arrays.
