Write a program that uses the map template class to compute a histogram of positive numbers entered by the user. The map's key should be the number that is entered, and the value should be a counter of the number of times the key has been entered so far. Use - 1 as a sentinel value to signal the end of user input. 512355321-1Then the program should output the followings:The number 3 occurs 2 timesThe number 5 occurs 3 timesThe number 12 occurs 1 timesThe
