# Minimum element left from the array after performing given operations

Given an array **arr[]** of **N** integers, the task is to remove the elements from both the ends of the array i.e. in a single operation, either the first or the last element can be removed from the current remaining elements of the array. This operation needs to be performed in such a way that the last element left will have the minimum possible value. Print this minimum value.**Examples:**

Input:arr[] = {5, 3, 1, 6, 9}Output:1

Operation 1: arr[] = {5, 3, 1, 6}

Operation 2: arr[] = {5, 3, 1}

Operation 3: arr[] = {3, 1}

Operation 4: arr[] = {1}Input:arr[] = {2, 6, 4, 8, 2, 6}Output:2

**Approach:** This problem can be solved greedily, the element with the maximum value from either of the end needs to be removed in a single operation. Following this approach until only one element is left in the array will give us the minimum element from the original array in the end.

Below is the implementation of the above approach:

## C++

`// C++ implementation of the approach` `#include <bits/stdc++.h>` `using` `namespace` `std;` `// Function to return the minimum possible` `// value of the last element left after` `// performing the given operations` `int` `getMin(` `int` `arr[], ` `int` `n)` `{` ` ` `int` `minVal = *min_element(arr, arr + n);` ` ` `return` `minVal;` `}` `// Driver code` `int` `main()` `{` ` ` `int` `arr[] = { 5, 3, 1, 6, 9 };` ` ` `int` `n = ` `sizeof` `(arr) / ` `sizeof` `(arr[0]);` ` ` `cout << getMin(arr, n);` ` ` `return` `0;` `}` |

## Java

`// Java implementation of the above approach` `import` `java.util.*;` `class` `GFG` `{` `// Function to return the minimum possible` `// value of the last element left after` `// performing the given operations` `static` `int` `getMin(` `int` `arr[], ` `int` `n)` `{` ` ` `int` `minVal = Arrays.stream(arr).min().getAsInt();` ` ` `return` `minVal;` `}` `// Driver code` `public` `static` `void` `main(String[] args)` `{` ` ` `int` `arr[] = { ` `5` `, ` `3` `, ` `1` `, ` `6` `, ` `9` `};` ` ` `int` `n = arr.length;` ` ` `System.out.println(getMin(arr, n));` `}` `}` `// This code is contributed by 29AjayKumar` |

## Python3

`# Python3 implementation of the approach` `# Function to return the minimum possible` `# value of the last element left after` `# performing the given operations` `def` `getMin(arr, n) :` ` ` `minVal ` `=` `min` `(arr);` ` ` `return` `minVal;` `# Driver code` `if` `__name__ ` `=` `=` `"__main__"` `:` ` ` `arr ` `=` `[ ` `5` `, ` `3` `, ` `1` `, ` `6` `, ` `9` `];` ` ` `n ` `=` `len` `(arr);` ` ` `print` `(getMin(arr, n));` `# This code is contributed by AnkitRai01` |

## C#

`// C# implementation of the above approach` `using` `System;` `using` `System.Linq;` `class` `GFG` `{` `// Function to return the minimum possible` `// value of the last element left after` `// performing the given operations` `static` `int` `getMin(` `int` `[]arr, ` `int` `n)` `{` ` ` `int` `minVal = arr.Min();` ` ` `return` `minVal;` `}` `// Driver code` `public` `static` `void` `Main(String[] args)` `{` ` ` `int` `[]arr = { 5, 3, 1, 6, 9 };` ` ` `int` `n = arr.Length;` ` ` `Console.WriteLine(getMin(arr, n));` `}` `}` `// This code is contributed by Rajput-Ji` |

## Javascript

`<script>` `// javascript implementation of the above approach` ` ` `// Function to return the minimum possible` ` ` `// value of the last element left after` ` ` `// performing the given operations` ` ` `function` `getMin(arr, n)` ` ` `{` ` ` `var` `minVal = Math.min.apply(Math, arr);` ` ` `return` `minVal;` ` ` `}` ` ` `// Driver code` ` ` `var` `arr = [ 5, 3, 1, 6, 9 ];` ` ` `var` `n = arr.length;` ` ` `document.write(getMin(arr, n));` `// This code is contributed by aashish1995` `</script>` |
