Approach :

-Split all strings of file by Space
-iterate over String Array & store all the strings in HashMap as key & its value will be incremented by one each time repeating the string.
-compare & store the max count & its value while iterating

Code for this in python:

word_dict ={ }
with open('test.txt', 'r') as fs:
	for line in fs:
		word_list = line.split(' ')
		for word in word_list:
			if word_dict.has_key(word):
				word_dict[word] = word_dict[word]+1
			else:
				word_dict[word] = 1
				
for k,v  in word_dict.items():
	print "{} --> {}".format(k,v)
