Histogram of positive numbers

Program Plan:

Include required header file.

Include required “std” namespace.

Define main function

Declare a variable in “map” template class.

Initializes the variable “numbers” to “0”.

Display prompt statement.

Performs “while” loop. This loop will perform upto “numbers” equal to “-1”.

In this loop, first read the number from user.

If the number is not equal to “-1”, then check if the number is in map or not using “find” function.

If it is, then assign “mapResult[numbers]” is “1”.

Otherwise, increment the counter

Declare constant iter “result” in “map” template class.

Display the given result using “for” loop.

In java Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8, 1, 4, 6}, the function would return 6, since the subsequence {1, 4, 6} is the longest that is strictly increasing. Develop a function that takes a string…
