--description--

二项式系数nCk可以以三角形排列，Pascal的三角形，如下所示：

111121133114641151010511615201561172135352171 .........

可以看出Pascal三角形的前八行包含十二个不同的数字：1,2,3,4,5,6,7,10,15,20,21和35。

如果没有素数的平方除n，则正整数n称为squarefree。在Pascal三角形的前八行中的十二个不同数字中，除了4和20之外的所有数字都是无方形的。前八行中不同的无平方数字的总和为105。

找到Pascal三角形的前51行中不同的无平方数字的总和。

--hints--

euler203()应该返回34029210557338。

assert.strictEqual(euler203(), 34029210557338);

function euler203() {

  return true;
