 # JavaScript: Check whether three given integer values are in the range 50..99

## JavaScript Basic: Exercise-29 with Solution

Write a JavaScript program to check whether three given integer values are in the range 50..99 (inclusive). Return true if one or more of them are in the said range.

Pictorial Presentation: Sample Solution:

HTML Code:

``````<!DOCTYPE html>
<html>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>JavaScript program to check whether three given integer values are in the range 50..99 (inclusive). Return true if one or more of them are in the said range.</title>
<body>

</body>
</html>
```
```

JavaScript Code:

``````function check_three_nums(x, y, z)
{
return (x >= 50 && x <= 99) || (y >= 50 && y <= 99) || (z >= 50 && z <= 99);
}

console.log(check_three_nums(50, 90, 99));
console.log(check_three_nums(5, 9, 199));
console.log(check_three_nums(65, 89, 199));
console.log(check_three_nums(65, 9, 199));
```
```

Sample Output:

```true
false
true
true
```

Flowchart: ES6 Version:

``````function check_three_nums(x, y, z)
{
return (x >= 50 && x <= 99) || (y >= 50 && y <= 99) || (z >= 50 && z <= 99);
}

console.log(check_three_nums(50, 90, 99));
console.log(check_three_nums(5, 9, 199));
console.log(check_three_nums(65, 89, 199));
console.log(check_three_nums(65, 9, 199));
``````

## JavaScript: Tips of the Day

Returns the sum of the powers of all the numbers from start to end (both inclusive)

Example:

```const sumPower = (end, power = 2, start = 1) =>
Array(end + 1 - start)
.fill(0)
.map((x, i) => (i + start) ** power)
.reduce((a, b) => a + b, 0);
console.log(sumPower(10)); // 385
console.log(sumPower(10, 3)); // 3025
console.log(sumPower(10, 3, 5)); // 2925
```

Output:

```385
3025
2925
```
