Given an arraynums, returntrueif the array was originally sorted in non-decreasing order, then rotatedsomenumber of positions (including zero). Otherwise, returnfalse. There may beduplicatesin the original array. Note:An arrayArotated byxpositions results in an arrayBof the same length such tha...
Depending on the direction provided, this implementation compares the input with the sorted collection of the input list. However,this approach is inefficient as sorting is an expensive operation, especially on larger inputs. Moreover, it defeats the purpose of checking if the collection is sorted ...
If we go through the examples of the problem and stop at the very first explanation: Explanation:[1,2,3,4,5] is the original sorted array. You can rotate the array by x = 3 positions to begin on the the element of value 3: [3,4,5,1,2]. The definite article "the" is duplica...
