Python Evaluation

Problem Statement :

```The eval() expression is a very powerful built-in function of Python. It helps in evaluating an expression. The expression can be a Python statement, or a code object.

For example:

>>> eval("9 + 5")
14
>>> x = 2
>>> eval("x + 3")
5
Here, eval() can also be used to work with Python keywords or defined functions and variables. These would normally be stored as strings.

For example:

>>> type(eval("len"))
<type 'builtin_function_or_method'>
Without eval()

>>> type("len")
<type 'str'>

You are given an expression in a line. Read that line as a string variable, such as var, and print the result using eval(var).

NOTE: Python2 users, please import from __future__ import print_function.

Constraint
Input string is less than 100 characters.```

Solution :

```                            ```Solution in C :

eval(input())```
```

Down to Zero II

You are given Q queries. Each query consists of a single number N. You can perform any of the 2 operations N on in each move: 1: If we take 2 integers a and b where , N = a * b , then we can change N = max( a, b ) 2: Decrease the value of N by 1. Determine the minimum number of moves required to reduce the value of N to 0. Input Format The first line contains the integer Q.

Truck Tour

Suppose there is a circle. There are N petrol pumps on that circle. Petrol pumps are numbered 0 to (N-1) (both inclusive). You have two pieces of information corresponding to each of the petrol pump: (1) the amount of petrol that particular petrol pump will give, and (2) the distance from that petrol pump to the next petrol pump. Initially, you have a tank of infinite capacity carrying no petr

Queries with Fixed Length

Consider an -integer sequence, . We perform a query on by using an integer, , to calculate the result of the following expression: In other words, if we let , then you need to calculate . Given and queries, return a list of answers to each query. Example The first query uses all of the subarrays of length : . The maxima of the subarrays are . The minimum of these is . The secon

QHEAP1

This question is designed to help you get a better understanding of basic heap operations. You will be given queries of types: " 1 v " - Add an element to the heap. " 2 v " - Delete the element from the heap. "3" - Print the minimum of all the elements in the heap. NOTE: It is guaranteed that the element to be deleted will be there in the heap. Also, at any instant, only distinct element
