Create a function that takes a vector of vectors as an argument. Each inner vector has 2 elements. The first element is the numerator and the second element is the denominator. Return the sum of the fractions rounded to the nearest whole number.

Examples:

sum_fractions({{18, 13}, {4, 5}}) ➞ 2

sum_fractions({{36, 4}, {22, 60}}) ➞ 9

sum_fractions({{11, 2}, {3, 4}, {5, 4}, {21, 11}, {12, 6}}) ➞ 11

Notes Your result should be a number not string.

CODE:

#include <bits/stdc++.h>
using namespace std;

//defining sum_fractions function
int sum_fractions (vector<vector<int>>v)
{
// Initialising sum variable to store the sum of the fractions  
double sum=0.0;

// storing the size of the vector in size
int size = v.size();


// iterating through all the vector pairs
for(int i=0;i<v.size();i++)
{   
        // adding the fraction to the sum, typecasting the numerator to double to get accurate results
        sum = sum + (double)v[i][0]/v[i][1];
}

// returning the rounded value
return round(sum);

}

In C++, create a function exchangesl that takes an argument of an array of integers ( for C++ use implement void exchangesl(vector<int>& a) . Those integers need to be changed so that the smallest and largest values in the array are exchanged. Assume that there is at least one element, if the largest value occurs more than once then exchange the first instance, if the smallest value happens more than once then exchange the last instance.

Add a new function that takes a phrase as an argument and counts each unique word in the phrase. The function should return a list of lists, where each sub-list is a unique [word, count] pair. Hint: A well-written list comprehension can solve this in a single line of code, but this approach is not required.

Python please Write a function that takes a string as an argument checks whether it is a palindrome. A palindrome is a word that is the same spelt forwards or backwards. Use similar naming style e.g. name_pal. E.g. If we call the function as abc_pal(‘jason’) we should get FALSE and if we call it a abc_pal(‘pop’) we should get TRUE. Hint: define your function as abc_pal(str). This indicates that string will be passed. Next create two empty lists L1=[] and...
