Step by Step solution about How to resolve the algorithm Sum of squares step by step in the Tcl programming language

Source code in the tcl programming language

package require Tcl 8.6
namespace path ::tcl::mathop

# {*} is like apply in Scheme--it turns a list into multiple arguments
proc sum_of_squares lst {
    + {*}[lmap x $lst {* $x $x}]
}
puts [sum_of_squares {1 2 3 4}]; # ==> 30
puts [sum_of_squares {}];        # ==> 0
