React Js Find Minimum Pair Sum in list
React Js Find Minimum Pair Sum in list:To find the minimum pair sum in a list using React.js, you can create a component that takes an array of numbers as input. Inside the component, you can initialize a variable to store the minimum sum, then use nested loops to iterate through all possible pairs of numbers in the list. For each pair, calculate the sum and compare it to the current minimum. Update the minimum if a smaller sum is found. Finally, display the minimum pair sum. This React component can efficiently find the minimum pair sum in a given list of numbers, making use of React's state management and rendering capabilities.

How can you use React.js to find the minimum pair sum in a given list of numbers?
This React.js code defines a component, "App," that finds the minimum pair sum in a list of numbers. It utilizes React hooks, specifically useState
, to manage state variables for the list of numbers, minimum pair, and minimum sum. When the "Find Minimum Pair Sum" button is clicked, it sorts the numbers, iterates through them to find the pair with the smallest sum, and updates the state with this information. The result is displayed in the component, showing the original list of numbers, minimum pair sum, and the pair itself. If there are fewer than two numbers, it displays an alert message.

<script type="text/babel">
const { useState, useEffect } = React;
function App() {
const [numbers, setNumbers] = useState([4, 2, 4, 7, 2, 1, 10, 8, 6]); // Replace with your numbers
const [minPair, setMinPair] = useState([]);
const [minSum, setMinSum] = useState(null);
const findMinimumPairSum = () => {
if (numbers.length < 2) {
alert("There should be at least two numbers to find a pair sum.");
return;
}
// Sort the array in ascending order
const sortedNumbers = [...numbers].sort((a, b) => a - b);
// Initialize the minimum sum and pair
let minSum = Number.MAX_VALUE;
let minPair = [];
// Iterate through the sorted array and find the minimum sum
for (let i = 0; i < sortedNumbers.length - 1; i++) {
let sum = sortedNumbers[i] + sortedNumbers[i + 1];
if (sum < minSum) {
minSum = sum;
minPair = [sortedNumbers[i], sortedNumbers[i + 1]];
}
}
setMinSum(minSum);
setMinPair(minPair);
};
return (
