Q1. [10 marks] Consider the algorithm SELECTIONSoRT shown below, where arr[i] arr[j] swaps the values of the given array elements and takes a constant number of basic operations. What is the worst case time complexity (using Big-Oh) of this algorithm? Justify your answer. Algorithm sELECTIONSoRT (arr,n) 1: if n1 2: return arr 3: for i=0 to n2 4: for j=i+1 to n1 5: if arr[i]>arr[j] 6: arr[i]arr[j]
