 # Programming-Idioms # Idiom #191 Check if any value in a list is larger than a limit

Given a one-dimensional array a, check if any value is larger than x, and execute the procedure f if that is the case

``for v in a do if v > x then f;``
``````unsigned i;
for (i = 0; i < sizeof(a) / sizeof(a); ++i) {
if (a[i] > x) {
f();
break;
}
}
``````
``#include <algorithm>``
``````if (std::any_of(a.begin(), a.end(), [x](auto y) { return y > x; }))
f();``````
``using System.Linq;``
``````if (a.Any(e => e > x))
f();``````
``if (a.any((value) => value > x)) f();``
``if (any(a > x)) call f``
``````for _, v := range a {
if v > x {
f()
break
}
}``````
``````if (a.any { it > x })
f()``````
``when (foldl1 (||) \$ map (a > x)) f``
``````if(a.some(item => item > x)){
f()
}``````
``````for(int value : a) {
if(value > x) {
f();
break;
}
}``````
``````for(int i = 0; i<a.length;i++) {
if(a[i]>x) {
f();
break;
}
}``````
``````if (count(array_filter(\$a, function(\$v) { return \$v > \$x; })))
f();

// or with intermediate steps
\$tmp = array_filter(
\$a,
function (\$v) { return \$v > \$x; }
)
if (count(\$tmp))
f();

// or with array reduce instead
if (
array_reduce(\$a,
function(\$old, \$item) { return \$old or (\$item > \$x); }
)
)
f();

// Array reduce takes the old result \$old, and
// applies \$item (from \$a) to the old result
// iteratively. We use the 'or' boolean operator
// to implement an 'any' operation.
``````
``use List::Util qw(any);``
``f if any { \$_ > \$x } @a;``
``````if any(v > x for v in a):
f()``````
``f if a.any?{|v| v > x }``
``````if a.iter().any(|&elem| elem > x) {
f()
}``````
``````(let iter ((l a))
(cond ((null? l) '())
((> (car l) x) (f))
(else (iter (cdr l)))))``````
