Function std.algorithm.searching.minPos
Returns the position of the minimum element of forward range rangerangerangeany other ordering
predicate (that's why maxPos is not provided).
Prototype
Range minPos(alias pred, Range)( Range range ) if (isForwardRange!Range && !isInfinite!Range && is(typeof(binaryFun!pred(range.front, range.front))));
Example
int[] a = [ 2, 3, 4, 1, 2, 4, 1, 1, 2 ];
// Minimum is 1 and first occurs in position 3
assert(minPos(a) == [ 1, 2, 4, 1, 1, 2 ]);
// Maximum is 4 and first occurs in position 2
assert(minPos!("a > b")(a) == [ 4, 1, 2, 4, 1, 1, 2 ]);
