Create a map mp, to store key-value pair, i.e. element-frequency pair. Traverse the array from start to end. Store the element-frequency pair in a vector and sort the vector in decreasing order of frequency.
Count occurrences of a number in a sorted array with duplicates
WebStep 1: Create a hash map, where key is the element and value is the frequency of occurrence of that element in the input array. Step 2: Using a loop, iterate over the elements and increase its value by 1 in the hash map created in the previous step. Step 3: Set the len as the 'MAP.SIZE'.
