Great job Jacob05. Your solution is more efficient. Solution below as solved by someone on my team bcscale(25); $itotal = "0"; $xt = "0.7893";$ii = 1; $yyy = "1";while ($ii <= 5000) { $y2 = intval(gmp_add($yyy,"1" ); $y3 = strval($y2); $factit = gmp_fact($y2); $at = bcdiv(gmp_mul("2", gmp_sub($factit,"1" ), $factit); $xtpow = bcpow($xt,$y2); $anst = bcmul($at,$xtpow); $itotal = bcadd($itotal,$anst); $yyy = gmp_add($yyy,"1" ; $ii++; }
echo "Solution: " .$itotal."<br />"; |

Bola discovered a mysterious piece of paper, containing a mysterious formula:
x^2 + (5/3)x^3 + (23/12)x^4 + (119/60)x^5 ... + (2*[5000!-1]/[5000!])x^5000
Bola was curious, and so decided to evaluate the expression for x=0.7893
What number was returned, to the nearest 20 decimal places? |

Programming / Simple Algorithm Challenge by Slyr0x: 9:07pm On May 15, 2016 |
Taye and Kenny were in class. They both tried to describe a man that was once sick. Taye said "The man had a cold." Kenny said "The man had had a cold." According to English grammar, Kenny was correct.
Now imagine their two teachers, Seun and Tony: Tony was a little off, and said that "Taye, while Kenny had had 'had had', had had 'had'; 'had' had had the better grammar." Seun corrected him, saying "Kenny, while Taye had had 'had', had had 'had had'; 'had had' had had the better grammar."
Continuing this pattern, the knowledgeable supervisor would note that "Seun, while Tony had had 'had had had had had had had had had had', had had 'had had had had had had had had had had had'; 'had had had had had had had had had had had' had had the better grammar."
Continuing this, how many 'had's would be in the incorrect 100th iteration? |

When you run it, it asks for a password. We need to get that pass. The pass has been defined "txtPass". Cheers |

Story sounds like something that was made up.
I assume an audit firm would have a formal termination procedure. Your direct boss has no business directly sacking you, as that is the HR Partner/Manager's responsibility.
In addition, as part of this "formal termination procedure", an audit firm would atleast have "Warning", "Suspension", and then dismissal.
Anyways, what do I know? 6 Likes 4 Shares |
