Code Report Solutions
Following are some simple solutions to videos found on YouTube. Idea is to make it easier for comparing and learning z^3 and other beautiful languages.
Number of Different Integers in a String
Video: https://www.youtube.com/watch?v=59vAjBS3yZM [APL Wins (vs C++, Java & Python)]
z^3 Solution
s="ad3343sadfsd343434df343443sff"; (s#/[^\d]+/)∪
Result: 3343 343434 343443
- splits string using the postfix regexp pattern. ∪ extracts unique from the results
// 12 Character z^3 Solution vs. 14 Character APL Solution
Final Value of Variable After Performing Operations

z^3 Solution
z=["--X","X++","X++"]; // todo
Count Negative Numbers in a Sorted Matrix
Video: https://www.youtube.com/watch?v=bXsKo2ZhgTg
z^3 Solution
x=[-2,-1,0;-1,1,3;-1,2,4]; (x⍌).findv(NEGATIVE)#
Gives answer 4
// ⍌ Flatten Array // findv Gives result of function call NEGATIVE // # Counts the result // Also note simpler z^3 Array Notation used to create the variable x (with , and ;). Usual Javascript array notations also work.
