JavaScript Basic: Exercise-55 with Solution

Write a JavaScript program to check whether a given string contains an equal number of p's and t's.

Pictorial Presentation:

Sample Solution:

HTML Code:

``````<!DOCTYPE html>
<html>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>check whether a given string contains equal number of p's and t's</title>
<body>

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

JavaScript Code:

``````function equal_pt(str)
{
var str_p = str.replace(/[^p]/g, "");

var str_t = str.replace(/[^t]/g, "");

var p_num = str_p.length;
var s_num = str_t.length;

return p_num === s_num;

}
console.log(equal_pt("paatpss"));
console.log(equal_pt("paatps"));
```
```

Sample Output:

```false
false
```

Flowchart:

ES6 Version:

``````function equal_pt(str)
{
const str_p = str.replace(/[^p]/g, "");

const str_t = str.replace(/[^t]/g, "");

const p_num = str_p.length;
const s_num = str_t.length;

return p_num === s_num;

}
console.log(equal_pt("paatpss"));
console.log(equal_pt("paatps"));

Example:

```const parseCookie = str =>
str
.split(';')
.map(v => v.split('='))
.reduce((acc, v) => {
acc[decodeURIComponent(v[0].trim())] = decodeURIComponent(v[1].trim());
return acc;
}, {});
console.log(parseCookie('foo=bar; equation=E%3Dmc%5E2')); // { foo: 'bar', equation: 'E=mc^2' }
```

Output:

```[object Object] {
equation: "E=mc^2",
foo: "bar"
}
```
