okay building simple postfix calculator in java , asked create couple functions it, 1 struggling memory. heard hashmap, , did research on it, don't think quite understand how implement program yet. way program work user start , postfix calculator , prompted input this: java postfixcalc integer postfix calculator memory > but has option assign variable input, example: > = 3 5 + 1 - 7 > bee = 3 * 21 > bee + 28 > bee 3 % 0 > = 4 4 > 57 57 > 2 c + c not found > mem a: 4 bee: 21 > exit here's code far. im figuring should tokenize input , put in array list first in order variable name, unless theres better way. import java.util.*; import java.io.*; public class program6 { public static void main(string args[]) { system.out.println("servando hernandez"); system.out.println("rpn command line calculator"); scanner scan = new scanner(system.in); system.out.print(">"); ...

javascript - check if function is a generator -

i played generators in nodejs v0.11.2 , i'm wondering how can check argument function generator function. i found way typeof f === 'function' && object.getprototypeof(f) !== object.getprototypeof(function) i'm not sure if (and working in future) way. what opinion issue? we talked in tc39 face-to-face meetings , deliberate don't expose way detect whether function generator or not. reason function can return iterable object not matter if function or generator function. var iterator = symbol.iterator; function notagenerator() { var count = 0; return { [iterator]: function() { return this; }, next: function() { return {value: count++, done: false}; } } } function* agenerator() { var count = 0; while (true) { yield count++; } } these 2 behave identical (minus .throw() can added too)

from matplotlib examples : import numpy np import seaborn sbs import matplotlib.pyplot plt r = np.arange(0, 3.0, 0.01) theta = 2 * np.pi * r ax = plt.subplot(111, polar=true) ax.plot(theta, r, color='r', linewidth=3) ax.set_rmax(2.0) ax.grid(true) ax.set_title("a line plot on polar axis", va='bottom') plt.show() how move radial tick labels (0.5, 1.0, 1.5, 2.0) different angle, 120 deg? with version 1.4 or later, can use "set_rlabel_position". e.g. place radial ticks long line at, say, 135 degrees: ax.set_rlabel_position(135) the relevant documentation residing here , bit hidden under "projections". adding line above yields (i don't have seaborn has default matplotlib formatting): prior 1.4, ax.set_rgrids can take angle argument.
