Coding Challenge November 2019 For Students @Chiang Mai<\/h2>\n

Coding Instructions:<\/strong>
\nThe following German words represent a mathematical formula:
\nHIER + GIBT + ES = NEUES<\/strong><\/p>\n

Conditions:<\/strong>
\n– every letter symbolizes one digit [0..9]
\n– the 10 different letters have to be 10 different digits
\n– every word is an unsigned integer number (no leading zeros)<\/p>\n

\n

Example 1:<\/strong><\/p>\n\n\n\n\n
H<\/td>\nI<\/td>\nE<\/td>\nR<\/td>\nG<\/td>\nB<\/td>\nT<\/td>\nS<\/td>\nN<\/td>\nU<\/td>\n<\/tr>\n
9<\/td>\n8<\/td>\n7<\/td>\n6<\/td>\n5<\/td>\n4<\/td>\n3<\/td>\n2<\/td>\n1<\/td>\n0<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

HIER + GIBT + ES = NEUES<\/strong>
\n9876 + 5843 + 72 = 17072<\/u>
\n\u274c Not correct<\/p>\n

\n

Example 2:<\/strong><\/p>\n\n\n\n\n
H<\/td>\nI<\/td>\nE<\/td>\nR<\/td>\nG<\/td>\nB<\/td>\nT<\/td>\nS<\/td>\nN<\/td>\nU<\/td>\n<\/tr>\n
0<\/td>\n1<\/td>\n2<\/td>\n3<\/td>\n4<\/td>\n5<\/td>\n6<\/td>\n7<\/td>\n8<\/td>\n9<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

HIER + GIBT + ES = NEUES<\/strong>
\n0<\/u>123 + 4156 + 27 = 82927<\/u>
\n\u274c Not correct and must be no leading zeros<\/p>\n

\n

Example 3:<\/strong><\/p>\n\n\n\n\n
H<\/td>\nI<\/td>\nE<\/td>\nR<\/td>\nG<\/td>\nB<\/td>\nT<\/td>\nS<\/td>\nN<\/td>\nU<\/td>\n<\/tr>\n
4<\/td>\n2<\/td>\n0<\/td>\n1<\/td>\n6<\/td>\n5<\/td>\n3<\/td>\n8<\/td>\n9<\/td>\n7<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

HIER + GIBT + ES = NEUES<\/strong>
\n4201 + 6253 + 0<\/u>8 = 90708<\/u>
\n\u274c Not correct and must be no leading zeros<\/p>\n

\n

Challenge (Extra score):<\/strong>
\n– create a PHP class containing a private method that solves the problem mentioned
\n– “worst case” solution: brute force (1010<\/sup> iterations = 10,000,000,000 iterations)
\n– “best case” solution: use mathematical rules to reduce the amount of iterations of the problem (“if then continue”)
\n– use a counter variable to measure the amount of loops needed to find possible results<\/p>\n

Example:<\/strong><\/p>\n

$iterations = 0;\r\n[loops to assign digits to the letters]\r\n\u00a0\u00a0\u00a0\u00a0e.g.: H=9;I=8;E=7;R=6;G=5;B=4;T=3;S=2;N=1;U=0\r\n\u00a0\u00a0\u00a0\u00a09876 + 5843 + 72 !== 17072  \/\/ not a correct solution\r\n\u00a0\u00a0\u00a0\u00a0$iterations++\r\n[\/loops]\r\n<\/pre>\n
– the method should output all results – if there are any – including the amount if iterations needed
\n– use comments to describe the mathematical rules used to reduce the complexity of the task
\n– the first place goes to the correct solution having the least iterations<\/p>\n
\n
Our Prizes:<\/strong>
\n1st<\/sup>\u00a0Prize: Gift Voucher \u0e3f1,000.00 (Central Voucher or Major Voucher or Starbucks Voucher)
\n2nd<\/sup>\u00a0 till\u00a0 4th<\/sup> Prize: Gift Voucher \u0e3f750.00 (Central Voucher or Major Voucher or Starbucks Voucher)
\n5th<\/sup>\u00a0 till\u00a0 10th<\/sup> Prize: Starbucks Voucher \u0e3f300.00<\/p>\n
Please send your answer and attached PHP file with a copy of your student ID and mobile phone number for reference via email to<\/strong>: info@data-horizon.com<\/a><\/p>\n
Competition closes on the 1st<\/sup> of December 2019.
