Unique Values This function will receive a single map parameter known as a_map. a_map will contain a single letter as a string and numbers as values. This function is supposed to search a_map to find all values that appear only once in a_map. The function will create another map named to_ret. For all values that appear once in a_map the function will add the value as a key in to_ret and set the value of the key to the key of the value in a_map (swap the key-value pairs, since a_map contains letters to numbers, to_ret will contain Numbers to Letters). Finally, the function should return to_ret. Signature: public static HashMap<String, Integer> uniqueValues(HashMap<Integer, String> a_map) Example: INPUT: {0=M, 2=M, 3=M, 5=M, 6=n, 7=M, 9=M}OUTPUT: {n=6} INPUT: {0=A, 1=c, 2=c, 4=c, 5=a, 8=Q, 9=c}OUTPUT: {A=0, a=5, Q=8}
Look at the code.
State True/False: A set may contain a specific value more than once, however, only unique value will be stored. True False
