Playground failed questions explainer

Question

could there be a brief explanation of questions that we fail on playground, some are quite challenging and it will be nice if the answers are explained

Answer 1

and yes Jim Mbatia you have missed to replace greater than operator in for loop condition

for ($i=0; $i<5; $i++)

Firstly 5025 is concatenate answer of a and b for in which a=50 and b=25 now that is because loop is running from 0 to 5 excluding 5 means for 0,1,2,3,4 means 5 time the loop will run and execute it body

$a is 0 initiallyn and when it goes inside the loop first time incremented by 10 so after 5 time going 10+10+10+10+10=50 that's why $a =50 same with $b goes 5 times in loop and increment by 5 five times so
$b= 5+5+5+5+5=25 so concatenate answer is 5025

after 5 times the loop condition will be false and out of the loop and print 5025 as output

I hope it is clear now have some 🍎 🍎
