The ordered sequence basically is any sequence that has an order in corresponding to the elements. It can be numeric or alphabetical, ascending, or descending, anything. There are many functions for performing sorting, available in the NumPy library. We have various sorting algorithms likequicksort...

or negative. We will use theabs()method to convert the actual value into absolute value and then we will use thesort_values()method to sort the values by absolute values. This method works on a particular column and it can sort the values either in ascending order or in descending order...

distance of data points from one another). NumPy supplies this functionality through thenp.partitionfunction.np.partitiontakes an array and a numberk. The result is a new array with the smallestkvalues to the left of the partition and the remaining values to the right (in arbitrary order): ...
Sort the Array in Descending Order in C++ To sort array or containers present in C++ STL in decreasing order, we have to pass a third parameter calledgreater<type>()in thesort()function. This function performs comparison so that elements at the end are sorted in descending order. ...

If we are sorting right-to-left or bottom-to-top, we’ll need to sort indescendingorder, according to the location of the contour in the image (Lines 13 and 14). Similarly, onLines 18 and 19we check to see if we are sorting from top-to-bottom or bottom-to-top. If this is the...
