std::find in C++
Finds the element in the given range of numbers. Returns an iterator to the first element in the range [first,last) that compares equal to val. If no such element is found, the function returns last. Function Template :
InputIterator find (InputIterator first, InputIterator last, const T& val)
Input iterators to the initial and final positions in a sequence. The range
searched is [first,last), which contains all the elements between first and
last, including the element pointed by first but not the element pointed by last.
Value to be search in the range
Return Value :
An iterator to the first element in the range that compares equal to val.
If no elements match, the function returns last.
Input : 10 20 30 40 Output : Element 30 found at position : 2 (counting from zero) Input : 8 5 9 2 7 1 3 10 Output : Element 4 not found.
Original vector : 10 20 30 40 Element 30 found at position : 2 (counting from zero)
Time Complexity: O(n)
Auxiliary Space: O(1)
