WebBinary Insertion Sort Algorithm. Binary insertion sort for array A: Step 1: Iterate the array from the second element to the last element. Step 2: Store the current element A [i] in a variable key. Step 3: Find the position of the element just greater than A [i] in the subarray from A [0] to A [i-1] using binary search. WebJul 16, 2013 · A complex sorting function would be much simpler, but you can use binary sort also. This can best be achieved using lambdas. Refer to these links for implementation details: 1) Complex sort with multiple parameters? 2) Advanced sorting criteria for a list of nested tuples EDIT: According to hivert's comment, you can sort using itemgetter too.
