● sort the array in ascending order ● run a loop through that array counting distinct elements ● make an array of all those distinct elements using 2nd ●(we get number of distinct elements) & running through original array [we made array2] ● make array3 of same length of number of distinct elements(correspoding to elemnts of array2) ●make a loop for running in array of distinct elements(array3) & inside it a loop on original array counting number of times a particular elements comes & putting it in array3 //now U have distinct elemnts in array2 & correspoding number of times they repeated in array3 //now using that array 3 , U can find max number using Array.sort() & taking last element then matching that number in original non-sorted array & finding element repeated most time . NOTE : there is a direct way we can print every element with number of times they repeated only by using loops(& not creating any more array) but will not be able to store that information . [U can try it by yourself]

This probably isn't the best way to do it, but in case anyone wants to see a code example for it: int[] array = { 1, 2, 1, 3, 1, 4, 5, 6, 7, 8, 6, 1, 7, 8, 9, 0 }; //sorting by lowest to highest Array.Sort(array, (y, x) => y.CompareTo(x)); Dictionary<int, int> dict = new Dictionary<int, int>(); for(int i = 0; i < array.Length - 1; i++) { //if the neighbour is equal to the current if (array[i] == array[i + 1]) { //if it isn't present in the dictionary if(!dict.Keys.Contains(array[i])) { //add it and increment to the value dict.Add(array[i], 1); dict[array[i]]++; } else { //otherwise just increment dict[array[i]]++; } } } //finally, print the results to console foreach (KeyValuePair<int, int> kvp in dict) Console.WriteLine(
quot;num: {kvp.Key}\ncount: {kvp.Value}");
