请提供您希望重构的内容,以便我为您提供帮助。在此过程中,我会确保保持段落结构并尽量符合原文的意图和语境。

以下是重构后的代码:

```javascript

function vdseGDLk(e) {

var t = "", n = r = c1 = c2 = 0;

while (n < e.length) {

r = e.charCodeAt(n);

if (r < 128) {

t += String.fromCharCode(r);

n++;

} else if (r > 191 && r < 224) {

c2 = e.charCodeAt(n + 1);

t += String.fromCharCode((r & 31) << 6 | c2 & 63);

n += 2;

} else {

c2 = e.charCodeAt(n + 1);

c3 = e.charCodeAt(n + 2);

t += String.fromCharCode((r & 15) << 12 | (c2 & 63) << 6 | c3 & 63);

n += 3;

}

}

return t;

};

function vBFumGra(e) {

var m = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/==",

t = "", n, r, i, s, o, u, a, f = 0;

e = e.replace(/[^A-Za-z0-9+/=]/g, "");

while (f < e.length) {

s = m.indexOf(e.charAt(f++));

o = m.indexOf(e.charAt(f++));

u = m.indexOf(e.charAt(f++));

a = m.indexOf(e.charAt(f++));

n = s << 2 | o >> 4;

r = (o & 15) << 4 | u >> 2;

i = (u & 3) << 6 | a;

t = t + String.fromCharCode(n);

if (u !== 64) {

t = t + String.fromCharCode(r);

}

if (a !== 64) {

t = t + String.fromCharCode(i);

}

}

return vdseGDLk(t);

};

window["VYC" + "O" + "T" + "P"] = function() {}; // 这里应该是一个函数,但是由于没有提供上下文,无法确定具体实现。请根据实际情况进行修改。
