Function indexOfMax [src]

Returns the index of the largest number in a slice. O(n). slice must not be empty.

Prototype

pub fn indexOfMax(comptime T: type, slice: []const T) usize

Parameters

T: typeslice: []const T

Example

 test indexOfMax {
    try testing.expectEqual(indexOfMax(u8, "abcdefg"), 6);
    try testing.expectEqual(indexOfMax(u8, "gabcdef"), 0);
    try testing.expectEqual(indexOfMax(u8, "a"), 0);
}

Source

  pub fn indexOfMax(comptime T: type, slice: []const T) usize {
    assert(slice.len > 0);
    var best = slice[0];
    var index: usize = 0;
    for (slice[1..], 0..) |item, i| {
        if (item > best) {
            best = item;
            index = i + 1;
        }
    }
    return index;
}
