Perhaps you should try some spelling variations:
"case complexity and algorithm image" » "the complexity and algorithm image" (Expand search), "and complexity and algorithm image" (Expand search), "case complexity and algorithms image" (Expand search), "case complexity an algorithm image" (Expand search), "case complexity and algorithmic image" (Expand search)
"api python python python programming" » "api pythons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pitons python python programming" (Expand search), "rpa python python python programming" (Expand search), "manim python python python programming" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("case complexity and algorithm image") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"case complexity and algorithm image\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( case complexity and algorithm image ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("case complexity and algorithm image") OR ("api python python python programming"))*.
