Perhaps you should try some spelling variations:
"coder _ reprogramming algorithm complexity" » "coder _ programming algorithm complexity" (Expand search), "coder _ programming algorithms complexity" (Expand search), "coder _ reprogramming algorithms complexity" (Expand search), "coder _ reprogramming algorithmic complexity" (Expand search)
"manim python python python programming" » "manim pythons python python programming" (Expand search), "manim piton python python programming" (Expand search), "manim pitons python python programming" (Expand search), "monty python python python programming" (Expand search), "api python python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder _ reprogramming algorithm complexity\") OR (\"manim python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder _ reprogramming algorithm complexity ) OR ( manim python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder _ reprogramming algorithm complexity") OR ("manim python python python programming"))*.
