SpletSwapping is one of the concepts which is frequently used in programs. Swapping means the interchanging of values of variables. It is done with the data in memory. Swapping can be done either with the help of one temporary variable or … SpletThe obvious answer would be swapping with 5 because swapping with 2 would mean another swap with 5, which would result in 2 swaps for the same element, but to find the minimum number of swaps to sort the array, it only makes sense to swap with the number such that both the elements are swapped in the correct sorted order.
SpletBefore Swap: a=10 b:20. After Swap: a=20 b:10. We can see the above code will work finely for swapping of two variables but it takes extra memory. To save memory we can use the swapping formula: a=a+b; b=a-b; a=a-b; These methods are good when we want to work on two elements. What if there is a necessity to make swapping on the list of objects.
