        count = 0
        for j in range(i + 1, size, 1):
            if words[j] == words[i]:
                count += 1
 
        if count >= frequency:
            frequent_word = words[i]
            frequency = count

from collections import defaultdict

def mostFrequentWord(words):
    temp = defaultdict(int)
    size = len(words)
 
    for i in range(0, size, 1):
        temp[words[i]] += 1
 
    frequent_word = max(temp, key=temp.get)

    return frequent_word

lst = ["java", "c++", "c", "c#", "c", "go", "php", "java", "java", "c", "python", "php", "c"]

frequent_word = mostFrequentWord(lst)
