Auxiliary Space: O (n) for hashmap. Another Efficient Solution (Space optimization): we can find frequency of array elements using Binary search function . First we will sort the array for binary search . Our frequency of element will be ‘ (last occ – first occ)+1’ of a element in a array . Below is the implementation of the above approach:Use numpy.unique with return_counts=True parameter, which will return the count of each of the elements in the array. For selecting only the elements which appear above a certain frequency threshold, you can use: It worked . I need to take elements only with count greater than 5 (say).We use frequency tables to find descriptive statistics. These are values which help describe the set of data such as the mean, median and mode of a set of data. For example, A frequency table showing the ages of 25 25 students on a college course. The mode is 18 18. The median is the 13^ {th} 13th value which is 18 18.Organizing data into a group frequency table. The grouped frequency table should have about 10 intervals. A good strategy is to come up with some widths according to Guideline 2 and divide the total range of numbers by that width to see if there are close to 10 intervals. The width of the interval should be a relatively simple number (like 2, 5 ...1 Answer. Instead of using the FFT directly you can use MATLAB's periodogram function, which takes care of a lot of the housekeeping for you, and which will plot the X (frequency axis) correctly if you supply the sample rate.
