Hi @Somith
In this question what you can do is make 2 arrays: left and right.
In left array store the length of non-decreasing subarray ending at arr[i]. Create it while traversing on array from left to right.
Similarlry, in right array store the length of non-decreasing subarray ending at arr[i]. This time traverse on array from right to left.
Now find maximum value of (left[i] + right[i] - 1 ). This is your answer.

See i m sharing you the code along with all the comments and explanation. Have a look and try to dry run few cases then you will understand how all works :
