Type Function minMax [src]

Finds the smallest and largest number in a slice. O(n). Returns an anonymous struct with the fields min and max. slice must not be empty.

Prototype

pub fn minMax(comptime T: type, slice: []const T) struct { T, T }

Parameters

T: typeslice: []const T

Example

 test minMax {
    {
        const actual_min, const actual_max = minMax(u8, "abcdefg");
        try testing.expectEqual(@as(u8, 'a'), actual_min);
        try testing.expectEqual(@as(u8, 'g'), actual_max);
    }
    {
        const actual_min, const actual_max = minMax(u8, "bcdefga");
        try testing.expectEqual(@as(u8, 'a'), actual_min);
        try testing.expectEqual(@as(u8, 'g'), actual_max);
    }
    {
        const actual_min, const actual_max = minMax(u8, "a");
        try testing.expectEqual(@as(u8, 'a'), actual_min);
        try testing.expectEqual(@as(u8, 'a'), actual_max);
    }
}
