Find the element with highest occurrences in an array java
9 I have to find the element with highest occurrences in a double array I did it like this int max 0 for int i 0 i array length i int count 0 for int j 0 j array length j if array i array j count if count max max count The program works but it is too slow
Java number of times that the max value occurs in the array, Step 1 Sort the array in ascending order Step 2 start from the end of the array and count the number of adjacent elements which are equal For example if arr 6 3 1 3 4 3 6 5 after sort arr 1 3 3 3 4 5 6 6 And number of similar elements from end is 2 DeepenKshetri this is not the optimal way to perform this don t use this method
Find the N Most Frequent Elements in a Java Array Baeldung
This allows us to find the n most frequent elements in the array efficiently public static List Integer findByHashMapAndPriorityQueue Integer array int n Map Integer Integer countMap new HashMap For each element i in the array add it to the countMap and increment its count for Integer i array countMap put i
Most Frequent Element in an Array EnjoyAlgorithms, Solution steps Step 1 We initialize two variables outside the nested loops maxFreq to track the maximum frequency and mostFrequent to track the most frequent element Step 2 We run the outer loop from i 0 to n 1 and the inner loop from j 0 to n 1 to count the frequency
Maximum Occurrence in a Given Range GeeksforGeeks
Maximum Occurrence in a Given Range GeeksforGeeks, Case 1 The value of the numbers at index i and j for the given range are same i e arr i arr j Solving this case is very easy Since arr i arr j all numbers between these indices are same since the array is non decreasing Hence answer for this case is simply count of all numbers between i and j inclusive both i e j i 1
