题目描述
You think you can code?
This problem will test you on various basic programming techniques.
You are given two integers $N$ and $t$; and then an array $A$ of $N$ integers ($0$-based indexing).
Based on the value of $t$, you will perform an action on $A$.
$t$
Action Needed
$1$
Print $7$, regardless of the content of $A$
$2$
Print “Bigger” if $A[0] > A[1]$, or
Print “Equal” if $A[0] == A[1]$, or
Print “Smaller” otherwise (without the quotes);
Ignore other indices of $A$, if any
$3$
Print the median of three integers {$A[0]$, $A[1]$, and $A[2]$};
Ignore other indices of $A$, if any
$4$
Print the sum of all integers in $A$
$5$
Print the sum of all even integers in $A$
$6$
Apply modulo (%) $26$ to each integer in $A$,
Map integer $0$/$1$/$\ldots$/$25$ to character ‘a’/‘b’/$\ldots$/‘z’,
Finally, print the sequence of characters as a string (without the spaces)
$7$
a. Start from index $i = 0$;
b. Jump to index $i = A[i]$;
c. If the current index $i$ is outside the valid bound of [0..$N$-1], print “Out” and stop;
d. Else if the current index $i$ is index $N$-$1$, print “Done” and stop;
e1. Otherwise, repeat step b;
e2. If doing this leads to an infinite loop, print “Cyclic” and stop;
(all output are without the quotes)
-----Input-----
The first line of the input contains an integer $N$ and $t$ ($3 \leq N \leq 200000$; $1 \leq t \leq 7$).
The second line of the input contains $N$ non-negative $32$-bit signed integers.
-----Output-----
For each test case, output the required answer based on the value of $t$.
-----Scoring-----
There are $20$ hidden test cases that test various requirements of this problem.
All $20$ test cases will be tested.
Each hidden test case worth $5$ points (the $7$ sample test cases below worth $0$ point).
