5a23c84252665b21eecc7eb0 | I before E except after C | 5 | 302288 | i-before-e-except-after-c |
--description--
The phrase "I before E, except after C" is a widely known mnemonic which is supposed to help when spelling English words.
Using the words provided, check if the two sub-clauses of the phrase are plausible individually:
- "I before E when not preceded by C".
- "E before I when preceded by C".
If both sub-phrases are plausible then the original phrase can be said to be plausible.
--instructions--
Write a function that accepts a word and check if the word follows this rule. The function should return true if the word follows the rule and false if it does not.
--hints--
IBeforeExceptC
should be a function.
assert(typeof IBeforeExceptC == 'function');
IBeforeExceptC("receive")
should return a boolean.
assert(typeof IBeforeExceptC('receive') == 'boolean');
IBeforeExceptC("receive")
should return true
.
assert.equal(IBeforeExceptC('receive'), true);
IBeforeExceptC("science")
should return false
.
assert.equal(IBeforeExceptC('science'), false);
IBeforeExceptC("imperceivable")
should return true
.
assert.equal(IBeforeExceptC('imperceivable'), true);
IBeforeExceptC("inconceivable")
should return true
.
assert.equal(IBeforeExceptC('inconceivable'), true);
IBeforeExceptC("insufficient")
should return false
.
assert.equal(IBeforeExceptC('insufficient'), false);
IBeforeExceptC("omniscient")
should return false
.
assert.equal(IBeforeExceptC('omniscient'), false);
--seed--
--seed-contents--
function IBeforeExceptC(word) {
}
--solutions--
function IBeforeExceptC(word)
{
if(word.indexOf("c")==-1 && word.indexOf("ie")!=-1)
return true;
else if(word.indexOf("cei")!=-1)
return true;
return false;
